Herbal immunomodulators as add on treatment in asymptomatic and mildly symptomatic COVID-19 confirmed cases: findings from a prospective single centre clinical trial

Background: The aim of the present study was to evaluate safety and efficacy of Sri Sri TattvaTM immunity products, a combination of single herb and poly herb formulations in COVID-19 patients by assessing their clinical features and immune markers. The products when administered orally for a period of 14 days in COVID-19 patients demonstrated significant improvement in clinical symptoms.Methods: Patients with fever, cough, sore throat started responding to the treatment from day 3 and most of the patients were clinically free of symptoms by day 7. Early recovery from signs and symptoms was observed in most of the patients. Sri Sri TattvaTM immunity products has also demonstrated an excellent clinical improvement and immune markers including tumor necrosis factor (TNF-alfa), interleukin (IL-6), interferon (IFN-beta), D-dimer, ferritin, lactate dehydrogenease (LDH) and C-reactive protein (CRP) in COVID-19 patients.Results: The final results of this study showed that Sri Sri TattvaTM immunity products reduced the time to clinical cure and number of days in achieving negative real time polymerase chain reaction (RT-PCR) by early viral clearance when given along with standard of care thus reduced the duration of hospitalization.Conclusions: In the present study, 82% of COVID-19 patients cleared the virus within 10-14 days of study period reducing the duration of hospitalization. None of the patients progressed to severe COVID-19 and succumbed to the disease. This clearly indicates that Sri Sri TattvaTM immunity products when administered orally along with standard of care has definitive role in the management of COVID-19 patients

Experimental Investigation for Detecting Mitotic Cells in Medical Image using an Automated Algorithm

Cancer of the breast is a malignant tumour that originates in the cells of the breast tissue. It is by far the most common kind of cancer found in females around the world, with a projected 2.3 million new cases will be discovered in the year 2020 alone. It is projected that one in eight women will be diagnosed with breast cancer at some point in their life, despite the fact that breast cancer can also occur in men. Breast cancer is a complex condition that can arise from a diverse set of factors, express itself in a variety of ways, and can be treated in a variety of ways. Ductal carcinoma in situ, invasive ductal carcinoma, and invasive lobular carcinoma are all different subtypes. Both the available treatment options and the expected outcome of breast cancer are very variable depending on the particular subtype of the illness. Breast cancer risk factors include drinking alcohol and not getting enough exercise, as well as getting older, having a family history of the disease, having genetic mutations, being exposed to estrogens, and having a family history of the disease. There is not always a connection between having risk factors and developing breast cancer, despite the fact that there can be a link between the two. The prognosis and treatment options for breast cancer are highly dependent on the stage of the disease at the time of diagnosis. During staging, the extent to which the cancer has spread throughout the body and how far it has progressed are both measured. The TNM system, the IAFCM system, the ACM system, and the MPIG system are just few of the staging systems that are used to classify breast cancer. These staging systems consider not only the size of the tumor but also whether or not lymph nodes are involved and whether or not distant metastases are present. The severity of breast cancer symptoms can vary widely, depending not only on the subtype of the disease but also on how far along it has progressed. Alterations in the size or shape of the breast, discharge from the nipple, and alterations in the skin of the breast (such as redness or dimpling) are all common indications. On the other hand, not all cases of breast cancer present themselves in a visible manner, and mammography and other forms of routine screening may be able to detect some of these cases. Options for treating breast cancer vary depending on the patient's condition and the stage of the disease, as well as the patient's overall health and their preferences towards therapy. Common examples of medical interventions include surgery, radiotherapy, chemotherapy, hormone therapy, and targeted therapy. Other examples include. In certain cases, it may be appropriate to participate in more than one form of treatment

A novel nine base deletion mutation in NADH-cytochrome b5 reductase gene in an Indian family with recessive congenital methemoglobinemia-type-II

Recessive hereditary methemoglobinemia (RCM) associated with severe neurological abnormalities is a very rare disorder caused by NADH- cytochrome b5 reductase (cb5r) deficiency (Type II). We report a case of 11 month old male child who had severe mental retardation, microcephaly and gross global developmental delay with methemoglobin level of 61.1%. The diagnosis of NADH-CYB5R3 deficiency was made by the demonstration of significantly reduced NADH-CYB5R3 activity in the patient and intermediate enzyme activity in both the parents. Mutation analysis of the CYB5R gene revealed a novel nine nucleotide deletion in exon 6 leading to the elimination of 3 amino acid residues (Lys173, Ser174 and Val 175). To confirm that this mutation was not an artifact, we performed PCR-RFLP analysis using the restriction enzyme Drd I. As the normal sequence has a restriction recognition site for Drd I which was eliminated by the deletion, a single band of 603-bp was seen in the presence of the homozygous mutation. Molecular modeling analysis showed a significant effect of these 3 amino acids deletion on the protein structure and stability leading to a severe clinical presentation. A novel homozygous 9 nucleotide deletion (p.K173–p.V175del3) is shown to be segregated with the disease in this family. Knowing the profile of mutations would allow us to offer prenatal diagnosis in families with severe neurological disorders associated with RCM — Type II

PROCESSING AND PROPERTIES OF BORON CARBIDE WITH HAFNIUM DIBORIDE ADDITION

This article presents the results of investigations on densification, mechanical and electrical properties of boron carbide (B₄C) with the addition of HfB₂. High dense B₄C-HfB₂ (2.5-30 wt.%) composites were prepared by hot pressing at a temperature of 2173 K with 40 MPa mechanical pressure. The B₄C-HfB₂ composite mixture exhibited a better sintering aptitude compared with monolithic B₄C. Hardness and elastic modulus of B₄C-HfB₂ composites were measured to be in the range 36-28GPa and 465-525GPa respectively. Indentation fracture toughness of B₄C increased with HfB₂ content and obtained a maximum of 7 MPa.m 1/2 at 30 wt.% HfB₂, which is ∼3 times higher than the monolithic B₄C. Crack deflection was identified to be the major toughening mechanism in the developed composite. B₄C-10wt.% HfB₂ composite exhibited a maximum electrical conductivity of 7144 Ω-1m-1 which is 26% higher than the conductivity of monolithic B₄C (5639 Ω-1m-1) at 1373 K

Cow dung extract as a low-cost and natural sensitizer for zinc oxide nanoparticles photoanode based dye-sensitized solar cell: A novel initiative for waste to energy conversion

Cow dung extracts are prepared using ethanol and methanol as solvents. Electronic absorption spectra of cow dung extracts have exhibited wide absorption in the UV and visible region between 300 and 730 nm. The absorption of cow dung extracts showed variations in intensity and absorption peaks at different wavelengths, which can be attributed to presence of diverse photosynthetic pigments corresponding to polarity of applied solvents. The observed pigments of chlorophyll a, chlorophyll b and carotenoids in the cow dung extracts can be ascribed to the feeding behavior of the cow. The FTIR and UV–vis absorption results have disclosed that the sensitization of zinc oxide nanoparticles (ZnO NPs) photoanode is mainly due to the chlorophylls present in the cow dung extract. The methyl group in the chlorophyll molecules from ideal bond with ZnO NPs that enables transfer of electrons from chlorophyll molecules to conduction band of ZnO NPs. The solar cells sensitized with cow dung extract in methanol has delivered highest energy conversion efficiency of 0.102%, which can be ascribed to presence of relatively a greater number of photosynthetic pigments
