In last two decade world suffer with three epidemic diseases like SARS-CoV, H1N1 influenza, MERS –CoV and presently the world under a pandemic of Covid-19, out of these SARS-CoV, MERS –CoV and Covid-19 are form the same virus call as corona, which primary present on bats and transferred from animal to human, and then it transfer from human to human mostly by respiratory droplets or in the direct contact with the diseased person, these recurrent infection of corona virus is the burning issue in the word, so to avoid these recurrent infections good habitual behaviour with regular immune booster medicine should be taken which can be used in both normal and symptomatic patient for this Rasayan churna  is the best drug of choice as it is used for  rejuvenation therapy. From literally study from various recourses it is found that Rasayan churna have property anti-depressant, anti-xylotic, Immunomodulatory, Anti-diabetes, anti hypertensive, anti-inflammatory, Anti-toxic effects, Anti-arthritic, Anti-cancer effects, Anti-microbial effect, and Anti-oxidant which can be useful in preventive aspect of Covid -19 in all phase like normal individual, also can be used in asymptomatic patients and symptomatic patients, clinical study can be performed for the same to evaluate the result.

Background: For decades, Praziquantel has been the undisputed drug of choice for all schistosome infections, but rising concerns due to the unelucidated mechanism of action of the drug and unavoidable reports of emerging drug resistant strains has necessitated the need for alternative treatment drug. Moreover, current apprehension has been reinforced by total dependence on the drug for treatment hence, the search for novel and effective anti-schistosomal drugs. Uses: This study made use of bioinformatic tools to determine the structural binding of the Universal G4LZI3 stress protein (USP) in complex with ten polyphenol compounds, thereby highlighting the effectiveness of these recently identified ‘lead’ molecules in the design of novel therapeutics targeted against schistosomiasis. Upregulation of the G4LZI3 USP throughout the schistosome multifaceted developmental cycle sparks interest in its potential role as a druggable target. The integration of in silico tools provides an atomistic perspective into the binding of potential inhibitors to target proteins. Conclusion: This study therefore, implemented the use of molecular dynamic (MD) simulations to provide functional and structural insight into key conformational changes upon binding of G4ZLI3 to these key phenolic compounds. Post-MD analyses revealed unique structural and conformational changes in the G4LZI3 protein in complex with curcumin and catechin respectively. These systems exhibited the highest binding energies, while the major interacting residues conserved in all the complexes provides a route map for structure-based drug design of novel compounds with enhanced inhibitory potency against the G4LZI3 protein. This study suggests an alternative approach for the development of anti-schistosomal drugs using natural compounds.

Pneumocystis carinii pneumonia (PCP) is the most frequent opportunistic infection in patients with AIDS, occurring in 80% and recurring in 50% of patients within 12 months of the first episode. Prophylaxis for PCP is recommended if the CD4+ cell count is <200×106/l or 20% of the total lymphocyte count, or after an episode of PCP. The most effective prophylactic agent currently is trimethoprim-sulphamethoxazole and should be the drug of choice but alternatives such as aerosol pentamidine are being increasingly used for patients who cannot tolerate this combination or other oral preparations. If aerosol pentamidine is used and administered via a Respigard II Marquest nebulizer, the dosage should be higher than the currently recommended monthly dosage of 300 mg.

AbstractThe novel coronavirus disease 2019 (COVID-19) belongs to coronaviridae families, like sarbecovirus (SARS), and causes pyrexia, pertussis, and acute respiratory distress syndrome (ARDS) in major. Started from Wuhan, China now forced the World Health Organization (WHO) to call it a pandemic. These dreadful figures elevate the need for rapid action for a rapid diagnostic tool, an efficacious therapy, or vaccine for such widespread disease. Here we reviewed all the latest research and trials including conventional antiviral medicines that have a narrow and finite effect on COVID-19. Recently, some advances have been made by a nucleotide/nucleoside analogues (NUC) inhibitor (remdesivir), ivermectin (antiparasitic drug), and convalescent plasma, the later one has more recently been approved by the Food and Drug Administration (FDA). In addition, a clinical-grade soluble human angiotensin-converting enzyme (ACE2), named hrsACE2, was able to inhibit the infection of human blood vessel organoids, as well as the human kidney organoids, by the virus. As of now, innovative therapeutics based on the CRISPR/Cas13d might overcome the challenge of COVID-19 either as a treatment option or precise and rapid diagnostic tool due to its rapid and precise nature. In this updated comprehensive rapid review, we try to cover all recent findings in terms of genomics, diagnosis, prevention, and treatment.

AbstractNocardia species are an uncommon but important cause of keratitis. The purpose of this review is to discus previous published papers relation to the epidemiology, etiology, diagnosis and management of Nocardia keratitis. Nocardia asteroides is the most frequently reported from Nocardia keratitis. Pain, photophobia, blepharospasm and lid swelling are mainly clinical manifestations. Usual risk factors for Nocardia keratitis are trauma, surgery, corticosteroids, and contact lens wear. Several antibiotics were used for treatment of Nocardia infection but according to studies, topical amikacin is the drug of choice for Nocardia keratitis. Topical steroid should not prescribe in these patients. In conclusion, although Nocardia keratitis is rare, early diagnosis and treatment are essential to prevent any scar formation and preserve a good visual acuity.

MRSA infection can affect a wide array of individuals that may lead to treatment failure. Also, the infection has the potential to spread from one area to another particularly health care facilities or communities eventually causing minor outbreaks. With this premise, the study aimed to describe MRSA infections using the hospital-based data of a tertiary hospital in Bacolod City, Philippines, from 2010 to 2012. Specifically, this study aimed to evaluate the antimicrobial resistance ofS. aureusisolated from clinical specimens and to put emphasis on the prevalence of MRSA and Inducible Clindamycin Resistance. A total of 94 cases from 2010 to 2012 were diagnosed to haveS. aureusinfection using conventional bacteriologic methods. From these cases, 38 (40.6%) were identified as MRSA and 37 (39.4%) were inducible clindamycin resistant. Wounds and abscesses were considered to be the most common specimens with MRSA infections having 71.05% while blood was the least with 5.3%. For drug susceptibility, out of the 94S. aureuscases, including MRSA, 100% were susceptible to linezolid making it the drug of choice for this study. It was then followed by tetracycline having a mean susceptibility of 95%;, while penicillin G was ineffective with 94 cases having 0% susceptibility.
