It is conceivable that chronic immunosuppression associated with HIV infection may contribute to a tumor microenvironment

that facilitates tumor progression, growth, and dedifferentiation. While these relationships are far from established, it may be the case that small cell carcinoma of the anus is more likely to develop in such a microenvironment and that Inhibitors,research,lifescience,medical HIV infection is indeed a risk factor for this malignancy. Since small cell carcinoma of the anus is an extremely rare malignancy, a definitive understanding of its pathogenesis is not established. As more data accumulates to suggest a relationship between HPV infection and the development of small cell carcinoma of the anus, HPV-directed therapies could prove beneficial. Furthermore, vaccines against high-risk HPV may be protective against the development of this aggressive cancer. Finally, the role of HIV in the pathogenesis Inhibitors,research,lifescience,medical of small cell carcinoma of the anus is unclear and merits further study. Ultimately, more research is needed to more clearly delineate the relationships between HPV, HIV, and small cell carcinoma of the anus.

Pancreatic

cancer is the fifth most common cause of cancer related death in the United States (1). It is Inhibitors,research,lifescience,medical a deadly disease that is found to be distantly metastatic by radiographic imaging in up to two-thirds of new diagnoses. When distant metastases are not found, surgical Inhibitors,research,lifescience,medical resection is the only potentially curative therapy, yet 80% of newly diagnosed patients are not eligible for Capmatinib cost surgery because of metastatic or locally advanced disease at presentation (2,3). Even when patients with clinically localized pancreatic Inhibitors,research,lifescience,medical cancer undergo surgical resection there is still a high rate of treatment failure due to local tumor regrowth, incomplete resection, or metastatic disease. Non-metastatic but locally unresectable pancreatic cancer can be divided into two categories: (I) borderline resectable and (II) locally advanced disease. Borderline resectable pancreatic cancer can involve

the superior mesenteric vein (SMV) or portal vein (PV), the gastroduodenal or hepatic arteries, or less than half the circumference of the superior mesenteric artery (SMA). Locally advanced pancreatic cancer includes disease that encases more that Cell press 50% of the superior mesenteric artery (SMA) or celiac artery (CA), or invades or encases the aorta or involves lymph nodes that are outside of the resection field (4). While surgery remains the only potentially curative option for localized pancreatic cancer, the optimal initial treatment strategy when surgery is not possible is unknown. Three treatment strategies commonly employed in the current era include chemotherapy alone (C), concurrent chemoradiation therapy (CRT), or induction chemotherapy followed by chemoradiation therapy (CCRT).

6% CI95% [27.6–29.4%] vs. 27.7% CI95% [26.5–28.9%] (p = 0.047) for anti-HBc; 6.4% CI95% [5.6–7.2%] vs. 4.5% CI95% [3.9–5.1%] (p < 10−3) for HBsAg and 3.6% CI95% [3.4–3.7%] vs. 2.4% CI95%

[2.0–2.8%] (p = 0.001) for chronic carriers. Prevalence of anti-HBc and HBsAg increases significantly with age globally for both males and females (p < 10−3). The distribution of HBV markers per governorates and districts is illustrated in Table 1. After standardisation per age significant differences were observed between the two governorates according to anti-HBc prevalence (32.1% CI95% [28.9–32.7%] in Béja and 27.8% CI95% [26.8–28.8%] in Tataouine; p = 0.005) and HBsAg prevalence (4.2% CI95% [3.2–4.8%] in Béja in the north and

selleck chemicals 5.6% CI95% [5.2–6.2%] in Tataouine in the south; p = 0.001). No significant differences were noted according to chronic carriage prevalence between the two governorates (2.6% CI95% [1.9–3.1%] in Béja vs. 2.8% CI95% [2.6–3.4%] in Tataouine). When the inhibitors analysis was refined at the subgovernorate level, significant differences were noted between districts according to these three markers (all p values <10−3). Ras el oued and Dhiba (in the south) showed a higher prevalence for all HBV markers than the other districts. If HBV chronic carriage prevalence Rigosertib mouse (7.7 and 12.0%, respectively) is considered, these two districts are classified as areas of high endemicity. Khniguet eddhene (in the north) and Rmada est (in the south) show an HBV chronic carriage prevalence of 4.9 and 2.0%, respectively, and can then be classified as areas of intermediate endemicity. All other districts have HBV chronic carriage prevalence less than 2% and are thus classified as areas of low endemicity. Interestingly, the relative proportion of carriers among HBsAg positive subjects differ

significantly Unoprostone (p < 10−3) between districts, and ranges from 30 to 90% ( Fig. 1). Not surprisingly, the age-distribution of HBsAg, anti-HBc, and chronic carriage prevalence increased as endemicity decreased. The median age of all HBV infection markers was lower in hyperendemic areas as compared to intermediate and hypo-endemic ones. The median age for anti-HBc positive subjects was 24.3 years, 30.8 years, and 40.0 years (p < 10−3); for HBsAg positive subjects, was 16.9 years, 23.0 years, and 29.9 years (p < 10−3); and for chronic carriers, was 14.7 years, 24.7 years and 29.8 years (p < 10−3) for hyperendemic regions, intermediate endemic regions, and low endemic regions (p < 10−3), respectively. Similarly, the age at which half the population have been infected decreased significantly from low (60 years) to intermediate (40 years) and high endemic regions (10 years) ( Fig. 2a). The age distribution of anti-HBc and chronic carriage showed different patterns according to endemicity ( Fig. 2b). In a hyperendemic area, chronic carriage increased quickly and saturated after the age of 20 years.

Figure 4. Example of a 3D FLASH (fast low angle shot) dataset of a normal volunteer measured by the conventional head coil. A. Excellent T- contrast in the original transversal images. B. A strong signal inhomogeneity is obvious

in the reconstructed sagittal images … A very complex signal and texture situation is present in so-called single shot imaging techniques like echo planar imaging (EPI),11 where k-space is filled in one shot with multiple gradient echoes. This is achieved by a gradient scheme in which the upper corner of the k-space is reached by a single gradient pulse followed by a series Inhibitors,research,lifescience,medical of blips resulting in a rectangular movement through the kspace.This technique is very sensitive to local susceptibility artifacts, resulting in image distortions and strong T2* contrast Inhibitors,research,lifescience,medical dependence. Some special imaging techniques like spiral imaging can produce a very complex pattern in the image texture, since this single shot technique moves on a spiral through the k-space, which can be achieved by oscillating gradients with a phase Inhibitors,research,lifescience,medical shift of 90° in the x and y directions. This technique requires data interpolation in k-space to bring the

measured data onto a Cartesian coordinate system before .Fourier transform. This interpolation can produce spurious artifacts with the consequence that the image texture is dependent on k-space interpolation and image reconstruction. In addition, the problem of texture dependence on measuring technique is more complicated Inhibitors,research,lifescience,medical due to the large number of imaging sequences available on modern scanners, as illustrated in (Figure 5) Figure 5. Sketch of the family of imaging techniques available on modern scanners. There are many strategies of mixing spin HDAC inhibitor echoes with gradient echoes to speed up imaging time with the consequence of very complex image contrast and texture. CISS, constructive … Results

and discussion SNR dependence Figure 6 and 6b show Inhibitors,research,lifescience,medical the results of a FLASH experiment, in a normal volunteer for SNR dependence measurement of texture parameters. The measuring parameters of the FLASH experiment were: TR/TE/α = 2 ms/ 9 ms/30°; bandwidth (BW) = 195 Hz/pixel; MA = 512×512; FOV = 280 mm; TH = 2 mm; and acquisitions (AQ) = 1 to 324 resulting in an SNR = 1 to 18. next Texture parameters (SNR, entropy 5×5, correlation 5×5) of white matter, gray matter, and noise are shown as a function of the number of acquisitions (=SNR2). Figure 6c demonstrates that no texture can be measured in white matter using standard image resolution (0.5×0.5×2 mm3) as described above, since the SNR of white matter has the same characteristics as noise. In contrast, the SNR of gray matter reaches a nearly constant value at about 16 acquisitions and no further improvement can be reached due to the true underlying texture of the tissue.

Using global statistics on the scalp electric fields, we measured the performance difference (remembered–forgotten), that is, SMEs, computing the average mean activity in the time window from −2 to −1 sec. Paired TANOVAs for each condition yielded a marginal Autophagy inhibitor effect in the stay condition (P = 0.052) and no effect in the switch condition (P = 0.196). The same procedure Inhibitors,research,lifescience,medical was applied in the time interval from −1 to −0 sec and here again, we found an opposite pattern, this means a significant effect in the switch condition (P = 0.009) but no significant effect in the stay condition (P = 0.348). The spatial distribution of these effects was further displayed and explored on the scalp level with t-maps as shown

in Figure ​Figure44. Hence, these results suggest that the processing of subsequently Inhibitors,research,lifescience,medical remembered and forgotten words might differ in location and/or relative contribution of the brain structures across the entire epoch with an opposite pattern in the two time windows, showing the emergence of the SME in both conditions but in different time frames. Differences in amplitude independent of topography were analyzed based on the differences in GFP (see Figs. ​Figs.4,4, ​,5).5). In the −2 to −1 sec window, we observed that forgotten words were associated with a higher GFP than remembered words both in the stay condition

(t(20) = −4.47, P < Inhibitors,research,lifescience,medical 0.001) and in the switch condition (t(20) = −4.88, P < 0.001). In the interval between −1 and −0 sec, GFP results were similar, showing an effect in both conditions (t(20) Inhibitors,research,lifescience,medical = −3.54, P = 0.002) and (t(20) = −4.21, P < 0.001) in the stay and switch conditions, respectively. The significant t values were in all cases negative, indicating higher prestimulus activity for the subsequently forgotten versus the subsequently remembered items as previously shown

(Padovani et al. 2011). Figure 5 T-test differences in global field power (GFP): **: P < 0.01 and ***: P < 0.001. Note that the standard deviations of the mean values shown do not correspond Inhibitors,research,lifescience,medical to the standard deviation employed for the paired t-tests. (A) Time interval ... A post hoc TANOVA was computed to assess the possible interactions of a third factor, the instruction type (emotional, semantic) with the two factors already considered in the previous analyses, namely condition isothipendyl and performance. To compute these analyses, we have considered the data of only 14 subjects with a minimum number of 10 trials for each condition. The results showed neither triple interaction nor other effects, but only a main effect near to significance (P = 0.06) for condition and performance in the time window from −1 to 0 sec. This finding, taken with caution, provides an indication that collapsing the trial activity across instruction types was correct and confirms the validity of our analyses, although it suffers from a loss of sufficient trials.

The data reported were particle size, evaluated as the intensity obtained from three repeat measurements, and the polydispersity index [20]. Before measurement of zeta potential, nanoparticulate dispersions were diluted with MLN8237 chemical structure filtered

1mM NaCl solution (Millex-HV Filter, 0.45 μm, Millipore, Billerica, MA, USA) up to a count rate of 100 to 1000Kcps. All measurements were performed in triplicate. Evaluation of Entrapment Efficiency of NPs. Entrapment efficiency of DRZ loaded NPs was determined according to the previously reported method [20]. For the determination of the entrapment efficiency, the NPs were first separated from the aqueous suspension medium by ultracentrifugation Inhibitors,research,lifescience,medical at 40,000rpm for 30min using Optima Max XP ultracentrifuge (Beckman Coulter, USA). The entrapment efficiency was determined in triplicate

indirectly by analyzing the amount of free DRZ in supernatant. The free DRZ in supernatant was quantified by validated UV spectrophotometric method at 254nm. The entrapment efficiency of DRZ NPs was Inhibitors,research,lifescience,medical calculated as follows: Entrapment  efficiency=[Total  amount  of  DRZ  loaded−Free  DRZ  in  supernatant]Total  amount  of  DRZ  loaded  ×100. (3) In Vitro Drug Release of NPs. The in Inhibitors,research,lifescience,medical vitro drug release profiles of optimized, lyophilized, and sterilized DRZ loaded NPs were determined in 50mL simulated tear fluid, pH 7.4 (STF) using dialysis bags (Himedia Laboratories, India) at 37°C under magnetic stirring. At predetermined time intervals, 5mL aliquots were withdrawn from the medium and analyzed for DRZ Inhibitors,research,lifescience,medical by validated UV spectrometry. To determine the release behavior of free drug, in vitro study of DRZ solution (2% w/v) was also performed as control experiment [20]. Studies were performed in triplicates and data was analyzed for release kinetics. Inhibitors,research,lifescience,medical In Vitro Mucoadhesion of NPs. The binding efficiency of mucin to NPs was determined by mixing 2mL of mucin (625μg/mL) with the same volume of NPs. NPs were previously ultra centrifuged at 40,000rpm for 30min and resuspended in distilled water. After incubation at 37°C for 30min, the samples

were ultracentrifuged at 40,000rpm for 30min. The concentration of free mucin in the supernatant was determined at 555nm by periodic acid/Schiff (PAS) colorimetric method [21, 22]. The mucin binding efficiency of NPs was calculated from the following equation: Mucin  binding  efficiency  (%)=[(C0−Cs)C0]×100, out (4) where C0 is the initial concentration of mucin used for incubation and Cs is the concentration of free mucin in the supernatant. FT-IR Spectroscopy and DSC Analysis of NPs. IR spectra and DSC thermograms of lyophilized OCM-CS and CS NPs (without cryoprotectant) were obtained to study any possible interaction and to characterize the thermal behavior between polymers and DRZ. Morphological Characterization of NPs. Transmission electron microscopy (TEM) was used to examine the morphology of the OCM-CSNs.

asoca and may be explored for probable medicinal properties. In conclusion, present study indicates

that the flower and bark of S. asoca can be considered as a good source of gallic acid and ellagic acid. This information can also be used for authentication and quality evaluation of commercial samples. This is a continuation of our previous work where we had reported the presence of gallic acid in leaves that is quantified in the present study. The results provide an encouraging suggestion for the use of S. asoca leaves as an alternative source of gallic acid throughout the year in the absence JQ1 ic50 of flowering season. Moreover, we suggest using the superficial layer of the bark (which has a good antioxidant property) without harming the plant as a whole, thus stressing on the need for biodiversity conservation of such an important medicinal plant species.

“Medicinal plants are known potential source of many phenolic compounds and antioxidants. Among these, polyphenols in particular, have been recognized for antioxidant activity and many other health benefits.1 Phenolic and flavonoids, as natural antioxidants Panobinostat datasheet and free radical scavengers, have involved substantial interest due to their importance in food and pharmacological industry.2 Factors, such as geographic location, age of the plant, season, associated microflora, Thiamine-diphosphate kinase nutritional status, and environmental stress are known to influence the secondary metabolite profile of a particular plant species. Seasonal variation in trees, for example from dormant to active phase, brings progressive changes in traits like production

of phytochemicals.3 Besides, optimization of methods with respect to solvent system is important for determination or extraction of the phytochemicals from any plant species. Libraries ginkgo biloba L. (family Ginkgoaceae), commonly known as living fossil, harbors many beneficial medicinal properties. Traditionally, it has been used on an extensive basis, either as food or medicinal component, almost all over the world. The leaf extract of ginkgo contains pharmaceutically imperative flavonoids, glycosides and ginkgolides which expand blood flow, act as antioxidant and mainly used as memory enhancer and anti-vertigo. 4 The present study is focused on the evaluation of phytochemicals and antioxidants in leaf extracts of ginkgo along with the factorial analysis among locations × seasons, seasons × solvents and locations × solvents.

IHC analysis Changes in protein expression following transfection of colorectal tissues were observed in stained cells using Olympus BX60 microscope and image analySIS software. Adjacent normal tissue served as an internal control for positive staining and a negative control staining was carried out without the primary antibody. MMR Inhibitors,research,lifescience,medical protein staining was considered negative when all of

the tumour cell nuclei failed to react with the antibody. Results Optimization of MMR protein staining protocol Tissue processing has the greatest single impact on the end result of IHC and different tissue types often require slightly different pre-treatments for optimum results. To optimized staining protocols we employed the Closed Loop Assay Development (CLAD) for IHC (http://www.selleckchem.com/products/AP24534.html Figure 1). Figure 1 Closed loop assay development (CLAD) Optimal staining was achieved for hMSH6 using DABMap system,

however; acceptable stating for hMLH1, hMSH2 and hMPS2 was only achievable using UltarMap system. MMR protein Inhibitors,research,lifescience,medical expression IHC staining was performed on 33 colorectal cancer tissue specimens. Loss of MMR Inhibitors,research,lifescience,medical protein is defined as complete absence of nuclear staining within the tumour. While MMR proteins expression is defined as the presence of nuclear staining within the tumour regardless its intensity or the number of positive nuclei (Figures 2,​,33,​,44,​,55) Figure 2 hMLH1 expression.

The nuclei stained brown in hPMS2 positive tumours, while taking the blue colour of haematoxylin in hPMS2 negative tumours Of the tissue specimens in which acceptable immunostaining was achieved, three samples showed loss of one or more of the MMR proteins (Table 3). Both hMLH1 and hPMS2 proteins were not expressed in a 36 years old woman (case 3) with cancer of the caecum (Proximal to the splenic flexure). She had history of breast cancer on her mother and colorectal cancer on one of her grandfathers (undocumented weather on paternal or maternal side) (Figure 6).

SVP concentrations were calculated by comparing the weight of the microtube at each of the following

steps: empty, with the nanoparticle solution, with the supernatant discarded, and then after the incubator drying step. Groups of 3–10 mice were injected s.c. in the hind limb with PBS vehicle containing SVP-formulated or free antigens and adjuvants either in both limbs (30 µl volume per a single injection selleck inhibitor site, 60 µl total) or in a single limb (60 µl total volume). The standard SVP injection dose was 100 µg per animal (unless specified Libraries otherwise). A single time-point injection was used in cytokine production and T cell induction experiments, and prime-boost regimens (2–3 immunizations with 14 or 28-day intervals; detailed in figure legends) were used in experiments assessing antibody generation. Intranasal inoculation in both nares (60 µl total volume) was done at a single time-point under light anesthesia. 96-Well Costar

plates (Corning Inc., Corning, NY, USA) were coated with 100 µl per well of OVA protein (5 µg/mL) or prostatic acid phosphatase (PAP) protein (1 µg/mL; Virogen) and incubated overnight at 4 °C. Plates were washed three times with 0.05% selleck compound Tween-20 in PBS, 300 µl diluent (1% casein in PBS; Thermo Fisher, Waltham, MA, USA) was added to each well to block non-specific binding, and plates were incubated for at least 2 h at room temperature (RT). Plates were washed as described above, and serum samples were serially diluted 3-fold down the plate and incubated for 2 h at RT. Two columns of standards were included on each plate (anti-OVA monoclonal antibody, Abcam, Cambridge,

MA, USA) starting at 0.25 µg/mL and diluted 3-fold down the plate. Naive mouse serum was used as a negative control. Plates were washed and detection antibody (either biotinylated goat anti-mouse Ig (BD Biosciences, San Jose, CA, USA) or horseradish peroxidase (HRP)-conjugated goat anti-mouse IgG (Abcam)) was added to each well. For antibody isotyping, goat anti-mouse IgG1 (Southern Biotech, Birmingham, AL, USA) and anti-mouse IgG2c (Bethyl Laboratories, Montgomery, TX, USA) (both HRP-conjugated) were used. Plates were incubated in the dark for 1 h second at RT and washed (three times, with at least a 30-s soak between each wash). For plates with biotinylated antibodies, plates were incubated for 30 min in the dark at RT with streptavidin–HRP (BD Biosciences) and washed (three times, with at least a 30-s soak between each wash). TMB substrate (BD Biosciences, San Jose, CA, USA) was added, and plates were incubated for 10 or 15 min in the dark. The reaction was stopped by adding stop solution (2N H2SO4) to each well, and the OD was measured at 450 nm with subtraction of the 570 nm reading using a Versamax plate reader (Molecular Devices, Sunnyvale, CA, USA). Data analysis was performed using SoftMax Pro v5.4 (Molecular Devices).

Clinical tests of this hypothesis are needed to assess its validity. If the immune activation that accompanies MS supports a potential role for inflammation in the pathogenesis of mood disorders,

then anti-inflammatory medications might be expected to ameliorate depression. Statins, a family of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, are used primarily to reduce atherogenesis and cardiovascular morbidity. Recently they have also been shown to have immunomodulatory properties that might be of benefit Inhibitors,research,lifescience,medical for the treatment of autoimmune disorders, and are currently being investigated in clinical trials for their potential use in treating MS.121 Inhibitors,research,lifescience,medical Previous studies have also found that statins may be of benefit in the treatment of depression. Young-Xu and colleagues studied patients from an outpatient cardiology clinic, and found that long-term use of statins appeared to be associated with a reduced incidence of anxiety,

depression, and hostility.122 Analysis from the United Kingdom General Practice Research Database found that individuals currently on statins have a lower Inhibitors,research,lifescience,medical risk of developing depression.123 In a double-blind pilot study, subjects who took statins for 1 year were found to improve in ratings of depressive symptoms.124 A potential role of inflammation mediated by prostaglandin E2 (PGE2) in depression has recently been explored. As cyclo-oxygenase-2 (COX-2) inhibitors inhibit PGE2 production and the production of proinflammatory cytokines, there

are a growing number of investigations into a potential role for these medications for treating depression. Aspirin has been shown to dramatically Inhibitors,research,lifescience,medical accelerate the onset of action of a selective serotonin reuptake inhibitor (SSRI) in an animal model of depression.125 More persuasively, a double-blind placebo TGF-beta inhibitor controlled trial in 40 patients with MDD demonstrated that addition of celecoxib had significant therapeutic Inhibitors,research,lifescience,medical effects on the action of the antidepressant reboxetine compared with treatment with reboxetine and a placebo.126 The potential interrelatedness of treatments for depression and their impact on inflammation is Edoxaban suggested by vagus nerve stimulation (VNS). VNS therapy is an effective adjunctive treatment for chronic or recurrent treatment-resistant depression in adults. The mechanism of action of VNS and how it ameliorates depression is not known. A series of elegant studies by Tracey and colleagues have identified the cholinergic anti-inflammatory pathway as a neural, efferent vagus nerve-based mechanism that controls inflammation.127 Vagus nerve cholinergic signaling interacts with α-7nAchR on immune cells and inhibits the production of TNF and other proinflammatory cytokines and excessive inflammatory responses.

Overall, nonresponse

to treatment can be considered if the patient’s objective condition and subjective experience do not evolve favorably after a therapeutic trial that was coherent with Axis I and Axis II diagnoses, provided adequate pharmacological doses were used, initial physical disorders were controlled, and detrimental extraneous influences were eliminated. History Jean Esquirol (1772-1840), a student of Philippe Pinel, was the first to underline the importance of the statistical assessment of treatment response. He stated his faith in evaluation and statistics in his Dabrafenib in vivo treatise on clinical psychiatry, Des maladies mentales, considérées sous les rapports médical, hygiénique, et médicolégal Inhibitors,research,lifescience,medical (1838): “The physician … must give a sincere report of his cases of success and failure. … I love statistics in medicine because I believe that it is useful; therefore, I have been using statistics to help me in my research into mental Inhibitors,research,lifescience,medical illness for the last 30 years. Statistics is the best instrument to measure the influence

of locality, regimen, and treatment methods.“3 In his statistics on patients admitted to the Charenton hospital near Paris over an 8-year period, he reported that a proportion of 1:3 were cured and discharged; he added that the rate was as high as 1:2.33 if incurable Inhibitors,research,lifescience,medical patients were excluded from the analysis.3 In his textbook, Allgemeine Psychopathologie, Karl Jaspers (1883-1969) had a critical approach to using treatment Inhibitors,research,lifescience,medical response as an instrument of knowledge (therapeutischer Erfolg als Erkenntnismittel). He warned against the reticence to report treatment failure, particularly in psychotherapy, and against the physician’s complacent belief that the patient’s condition improved thanks to medical intervention.4 Therapeutic expectations change with the times. Today, treatment response is considered mostly in the context of pharmacotherapy, whose appearance in the 1950s considerably broadened our therapeutic armamentarium. Expectations were more

modest up to the second Inhibitors,research,lifescience,medical half of the 20th century, because therapeutic means were considerably less efficient. The foremost psychotropic agent was chloral, which was synthesized in 1832 and recognized as a useful hypnotic for anxious or depressed patients in 1869 by Matthias E. O. Liebreich (1839-1908), a pharmacologist in Berlin. The less severely ill ADP ribosylation factor could be managed with hypnotism, introduced by Franz Anton Mesmer (1734-1815) and developed by Jean-Martin Charcot (1825-1893), or by the “rest cure” introduced in 1875 by the American physician Silas Weir Mitchell (1829-1914) for the treatment of neurasthenia. Asylum was the only option for the severely ill. In the 19th century, it was accepted that some patients were incurable. A pessimistic course was part of the theory of degeneration (Bénédict-Augustin Morel [1809-1873]), which posited that the disease could only worsen from one generation to the next.
