Alzheimer’s disease (AD), a neurodegenerative disease, is the most common form of dementia. Inhibition of acetylcholinesterase (AChE) is a common strategy for the treatment of AD. In this study, aqueous, hydro-methanolic, and methanolic extracts of five potent herbal extracts were tested for their in vitro anti-AChE activity. Among all, the Tinospora cordifolia (Giloy) methanolic fraction performed better with an IC50 of 202.64 µg/mL. Of the HPLC analyzed components of T. cordifolia (methanolic extract), palmatine and berberine performed better (IC50 0.66 and 0.94 µg/mL, respectively) as compared to gallic acid and the tool compound “galantamine hydrobromide” (IC50 7.89 and 1.45 µg/mL, respectively). Mode of inhibition of palmatine and berberine was non-competitive, while the mode was competitive for the tool compound. Combinations of individual alkaloids palmatine and berberine resulted in a synergistic effect for AChE inhibition. Therefore, the AChE inhibition by the methanolic extract of T. cordifolia was probably due to the synergism of the isoquinoline alkaloids. Upon molecular docking, it was observed that palmatine and berberine preferred the peripheral anionic site (PAS) of AChE, with π-interactions to PAS residue Trp286, indicating that it may hinder the substrate binding by partially blocking the entrance of the gorge of the active site or the product release.

Introduction Interleukin (IL)-18 plays an important dual role in Th1 polarization and viral clearance, as well as in the development of liver fibrosis. Single-nucleotide promoter polymorphisms influence the transcription of IL-18 mRNA. Promoter polymorphisms are linked to delayed virus clearance and disease susceptibility in many diseases. However, there is no information about their role in hepatitis C virus (HCV) infection. Aim To investigate the association between -607 or -137 polymorphism with susceptibility and severity of HCV infection. Patients and methods Two hundred and four serologically proven patients with chronic HCV infection and 350 matched healthy controls were included in this study. Patients were segregated in 2 groups: group A with mild liver disease and group B with severe liver disease on the basis of histological activity index (HAI B5 or [5) and hepatic fibrosis score (B2 or [2). IL-18 promoter genotyping was performed with sequence-specific primers. Results There was no significant difference in the frequencies of -607 and -137 allelic distribution in patients and controls. The -607 A/A allele was more common in group A patients with mild liver disease than in patients with severe liver disease on the basis of HAI (38.6% vs.

(1) Background: Withania somnifera Dunal (Ashwagandha) is a widely used medicinal herb in traditional medicinal systems with extensive research on various plant parts. Surprisingly, seeds of W. somnifera have never been investigated for their therapeutic potential. (2) Methods: W. somnifera seeds were extracted for fatty acids (WSSO) using super critical fluid extraction, and was analyzed by gas chromatography. Its therapeutic potential in psoriasis-like skin etiologies was investigated using a 12-O tetradecanoyl phorbol 13-acetate (TPA)-induced psoriatic mouse model. Psoriatic inflammation along with psoriatic lesions and histopathological scores were recorded. WSSO was also tested on murine macrophage (RAW264.7), human epidermoid (A431), and monocytic (THP-1) cells, stimulated with TPA or lipo poly-saccharide (LPS) to induce pro-inflammatory cytokine (IL-6 and TNF-α) release. NFκB promoter activity was also measured by luciferase reporter assay. (3) Results: Topical application of WSSO with concurrent oral doses significantly reduced inflammation-induced edema, and repaired psoriatic lesions and associated histopathological scores. Inhibition of pro-inflammatory cytokines release was observed in WSSO-treated A431 and THP-1 cells, along with reduced NFκB expression. WSSO also inhibited reactive nitrogen species (RNS) in LPS-stimulated RAW264.7 cells. (4) Conclusion: Here we show that the fatty acids from W. somnifera seeds have strong anti-inflammatory properties, along with remarkable therapeutic potential on psoriasis-like skin etiologies.

Human Parvovirus B19 has been linked to a variety of diseases. One of the most common complications is transient aplastic crisis in patients with chronic hemolytic anemia. Very few case reports have implicated this virus as a putative etiology behind hepatitis and severe aplastic anemia in immuno competent individuals. We report a case of severe aplastic anemia in a previously healthy adult female due to acute parvovirus B19 infection. Laboratory examination showed pancytopenia in peripheral blood and severe hypoplastic bone marrow on biopsy. Serological analysis (ELISA) revealed acute Parvovirus B19 infection. In the face of unavailable HLA matched bone marrow donor, immuno-supressive therapy was contemplated, but could not be given because of financial constraints. Pancytopenia persists till date, 4 months after the diagnosis, with the patient requiring repeated packed red cell and irradiated platelet transfusions. Thus, acute infection with this virus must be considered a cause of acquired aplastic anemia even in individuals without underlying disease.

Balkrishna et al. Divya Sarva-Kalp-Kwath Attenuates Hepatotoxicity the literature search on the identified plant metabolites, SKK was found to act in multiple ways to ameliorate CCl 4 induced hepatotoxicity. Therefore, polyherbal SKK medicine has shown remarkable potentials as a possible alternative therapeutics for reducing liver toxicity induced by drugs, and other toxins.
