Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is recognized as one of the life-threatening viruses causing the most destructive pandemic in this century. The genesis of this virus is still unknown. To elucidate its molecular evolution and regulation of gene expression, the knowledge of codon usage is a pre-requisite. In this study, an attempt was made to document the genome-wide codon usage profile and the various factors influencing the codon usage patterns of SARS-CoV-2 in human and dog. The SARS-CoV-2 genome showed relative abundance of A and U nucleotides and relative synonymous codon usage analysis revealed that the preferred synonymous codons mostly end with A/U. The analysis of ENc-GC3s, Neutrality and Parity rule 2 plots indicated that natural selection and other undefined factors dominate the overall codon usage bias in SARS-CoV-2 whereas the impact of mutation pressure is comparatively minor. The codon adaptation index and relative codon deoptimization index of SARS-CoV-2 deciphered that human is more favoured host for adaptation compared to dog. These results enhance our understanding of the factors involved in evolution of the novel human SARS-CoV-2 and its adaptability in dog.Silkworms have been used as a host for the production of recombinant proteins in a baculovirus expression system using Bombyx mori nucleopolyhedrovirus (BmNPV). To coexpress several recombinant proteins, a silkworm must be coinfected with several recombinant BmNPVs, which requires a difficult DNA manipulation procedure. In this study, we constructed recombinant BmNPVs containing three expression cassettes, Rous sarcoma virus (RSV) Gag protein, surface antigen 1 of Neospora caninum (NcSAG1) and SAG1-related sequence 2 of N. caninum (NcSRS2), by Gibson assembly and the Bac-to-Bac system, designated BmNPV/SAG-SRS-Gag and BmNPV/SAG-Gag-SRS. BmNPV/SAG-SRS-Gag was expressed in silkworms and characterized. NcSAG1 and NcSRS2 were purified with RSV Gag proteins using sucrose density gradient centrifugation and affinity chromatography. RSV Gag formed virus-like particles (RSV-LPs) at a diameter of 20-30 nm based on transmission electron microscopy (TEM). Immuno-TEM analysis showed that both NcSAG1 and NcSRS2 were displayed on the surface of the RSV-LPs. These results indicate that RSV-LPs displaying two different kinds of proteins were produced in the hemolymph of silkworm larvae by the single polycistronic strategy. This expression platform is efficient for generating multiantigen-displaying VLPs and facilitates the development of vaccines against infectious diseases.
Obesity and metabolic syndrome are increasingly recognized as risk factors for development of hepatocellular adenoma (HCA). The implications of weight loss on HCA regression has not been previously reviewed.

To analyze the effects of surgical and nonsurgical weight loss on HCA.

University Tertiary Hospital.

Literature review of full-text articles from PubMed and Scopus on patients with HCA who underwent surgical or nonsurgical weight loss was performed. Only English language articles were included and editorial comments were excluded. Wilcoxon signed rank test was used for paired data analysis. check details Spearman correlation was used for correlation between percent excess weight loss (%EWL) and number and size of HCA lesions.

Out of 4 studies, 7 patients were included in this review, all of whom were female. The median preintervention body mass index was 41 kg/m
compared with the postintervention body mass index of 28 kg/m
(P = .002). The %EWL following intervention positively correlated to reduction in nrgical and nonsurgical methods result in regression of HCAs. Weight loss could avoid major liver resections or decrease the morbidity associated with liver surgery. Bariatric surgery should be considered as an option for management of surgically challenging HCAs in carefully selected obese patients. Multicenter long-term trials, while adjusting for cofounding factors, are required to determine the effects of surgical compared with nonsurgical weight loss on maintenance of HCA regression.
Many bariatric surgical centers mandate achieving weight loss targets through medical weight management (MWM) programs before offering bariatric surgery, but the evidence for this is unclear.

To examine the relationship between weight changes during (1) MWM, and (2) preoperative low-energy-diet (LED), and weight changes at 12 and 24 months after surgery.

Multicenter community- and acute-based MWM services referring to one regional bariatric center, United Kingdom.

A retrospective cohort study of patients who attended MWM and then underwent a primary laparoscopic bariatric procedure (adjustable gastric banding [LAGB], or Roux-en-Y gastric bypass [RYGB]) in a single bariatric center in the United Kingdom between 2013 and 2015. Data were collected from patient electronic records.

Two hundred eight patients were included (LAGB n = 128, RYGB n = 80). Anthropometric data were available for 94.7% and 88.0% of participants at 12 and 24 months, respectively. There was no relationship between weight loss duriot be denied bariatric surgery because of not achieving weight loss in MWM. Weight loss responses to preoperative LEDs as a predictor of postsurgical weight loss requires further investigation.
Bariatric surgery has been shown to produce the most predictable weight loss results, with laparoscopic sleeve gastrectomy (SG) being the most performed procedure as of 2014. However, inadequate weight loss may present the need for a revisional procedure.

The aim of this study is to compare the efficacy of laparoscopic resleeve gastrectomy (LRSG) and laparoscopic Roux-en-Y gastric bypass in attaining successful weight loss.

Public hospital following SG.

A retrospective analysis was performed on all patients who underwent SG from 2008-2019. A list was obtained of those who underwent revisional bariatric surgery after initial SG, and their demographic characteristics were analyzed.

A total of 2858 patients underwent SG, of whom 84 patients (3%) underwent either a revisional laparoscopic Roux-en-Y gastric bypass (rLRYGB) or LRSG. A total of 82% of the patients were female. The mean weight and body mass index (BMI) before SG for the LRSG and rLRYGB patients were 136.7 kg and 49.9 kg/m
and 133.9 kg and 50.
