Cancer is one of the most important mortality in the world. The major drawbacks of chemotherapy are the poor absorption of drugs into tumor tissues and development of resistance against anti-cancer agents. To overcome these limitations, the use of microorganisms has been extensively considered in the treatment of cancer. Microorganisms (bacteria/Archaea) secrete different bioactive compounds that can efficiently inhibit cancer cells growth. Biological nanocarriers derived from microorganisms including outer membrane vesicles (OMVs), bacterial ghosts (BGs) and archaeosomes have also been considered as drug delivery systems. Conjugation of drug loaded nanocarriers to bacteria strongly kills the cancer cells after internalization through the bacteria. Merging of microbiology and nanotechnology may provide versatile microbial nano-hybrids for promising treatment of cancer. This strategy causes more amount of drug to enter into cancer cells. In this review, we present evidence that microorganism, their derivatives as well as their intervention with nanotechnology can be a powerful vehicle for eradication cancer.

Phosphotyrosine Binding (PTB) Domains, usually found on scaffold proteins, are pervasive in many cellular signaling pathways. These domains are the second-largest family of phosphotyrosine recognition domains and since their initial discovery, dozens of PTB domains have been structurally determined.

Due to its signature sequence flexibility, PTB domains can bind to a large variety of ligands including phospholipids. PTB peptide binding is divided into classical binding (canonical NPXY motifs) and non-classical binding (all other motifs). The first atypical PTB domain was discovered in cerebral cavernous malformation 2 (CCM2) protein, while only one third in size of the typical PTB domain, it remains functionally equivalent.

PTB domains are involved in numerous signaling processes including embryogenesis, neurogenesis, and angiogenesis, while dysfunction is linked to major disorders including diabetes, hypercholesterolemia, Alzheimer's disease, and strokes. PTB domains may also be essential in infectious processes, currently responsible for the global pandemic in which viral cellular entry is suspected to be mediated through PTB and NPXY interactions.

We summarize the structural and functional updates in the PTB domain over the last 20 years in hopes of resurging interest and further analyzing the importance of this versatile domain.

To compare the safety of intermittent fasting (IF) with that of continuous energy-restricted diets (CERD) in patients with T2DM and metabolic syndrome who were overweight or obese and assess their effects on glycemic control and weight loss.

We searched MEDLINE (Ovid), Embase, and SINOMED databases up to September 13, 2020. The major outcome was glycemic control and secondary outcomes were change in weight, fasting insulin, and lipid profile.

Of 84 retrieved studies, 5 met our inclusion criteria. Of these, four studies comprising 355 participants were included in the meta-analysis. Based on changes in HbA1c (-0.06, 95% confidence interval [CI] -0.27 to 0.16) and fasting plasma glucose (-0.27, 95% CI -0.76 to 0.22), IF and CERD had similar effects on glycemic control. Moreover, IF had a better effect on weight loss (-1.70, 95% CI -3.28 to -0.11kg). Patients in both groups experienced similar improvements in fasting insulin and lipid profile as well as similar hypoglycemic events.

IF is a safe diet pattern and could be implemented for patients with T2DM or metabolic syndrome. Further studies with a larger sample size are needed to verify the effectiveness and safety of IF in patients with T2DM.

To evaluate whether the extent of return to fasting state 2-hours after a glucose challenge among normoglycemic individuals is associated with lower risk of incident prediabetes/ type 2 diabetes in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study.

We evaluated this association among 1879 normoglycemic adults who were categorized into three groups 'Low post load' (2hPG<FPG); 'Medium post load' (2hPG ≥ FPG and<75

percentile of the difference); and 'High post load' (2hPG>FPG and≥75

percentile of the difference). We used Cox proportional hazards regression to evaluate the association of the difference in 2hPG and FPG with incident diabetes/prediabetes after adjustment for demographic and clinical covariates.

During 20years of follow-up, 8% developed type 2 diabetes and 35% developed prediabetes. Compared to those with 'Low post load', the risk of type 2 diabetes was higher for participants with 'High post load' [HR 1.56, 95% CI (1.03, 2.37)] and similar for participants with 'Medium post load' [HR 0.99, 95% CI (0.64, 1.52)]. However, HRs for incident prediabetes among participants with 'High post load' [HR=1.2, 95%CI = (0.98, 1.46)] was not significantly different compared to participants with 'Low post load'.

Among normoglycemic individuals, a difference between 2hPG and FPG concentration>0.9mmol/L can be used to stratify individuals at higher risk for developing type 2 diabetes.

To identify the effects of the first lockdown in Germany (March to May 2020) on glycemic control, BMI, and cardiovascular risk factors in persons with type 2 diabetes.

The nationwide Disease Analyzer database includes a representative panel of physicianś practices in Germany providing anonymized real-world patient data. For metabolic and renal factors, we estimated absolute changes of means comparing outcomes from June to November 2020 to outcomes in the same persons from June to November 2019, and June to November 2018, respectively.

In 32,399 patients with type 2 diabetes, HbA1c change between 2019 and 2020 was+0.04% (95%CI 0.03%; 0.05%) compared to -0.02% (95%CI -0.03%; -0.01%) between 2018 and 2019. Metabolic risk factors and creatinine changed only little between June to November 2019 and June to November 2020. The proportions of patients with BMI≥30kg/m

were 56%, 55%, and 54% in June to November 2018, 2019, and 2020, respectively. The corresponding proportions for HbA1c>53mmol/mol Hb (>7.0%) were 39%, 39%, and 40%.

There is little evidence that the first COVID-19 lockdown in Germany had a short-term harmful influence on acute health care outcomes and vascular risk factors in people with type 2 diabetes.

Intensive glycemic therapy could lead to increased mortality in patients with type 2 diabetes mellitus (T2DM). But it remains unclear whether statins use improves prognosis in T2DM patients with intensive glycemic therapy.

Using data from Action to Control Cardiovascular Risk in Diabetes trial and performing propensity score matching and Cox proportional hazards regression, we explored the relationship between statin use and the risk of mortality in intensive-therapy group.

In the intensive-therapy group, total mortality (TM) in patients with statins treatment is lower than those without statins (hazard ratio (HR), 0.68; 95% confidence interval (CI) 0.49-0.95; P=0.022); the effects of statins on cardiovascular mortality (CM) and primary outcomes (PO), however, were negligible (CM HR 0.96; 95% CI 0.61-1.51; P=0.854; PO HR 0.88; 95% CI 0.65-1.19; P=0.415). Besides, the risk of TM, CM and PO in patients with the intensive therapy combined with statins use was similar to those in the standard group (TM P=0.445; CM P=0.362; PO P=0.637).

Statins may alleviate the risk of TM in T2DM patients receiving intensive glycemic therapy.

Statins may alleviate the risk of TM in T2DM patients receiving intensive glycemic therapy.The influenza A virus genome contains 8 gene segments encoding 10 commonly recognized proteins. Additional protein products have been identified, including PB1-F2 and PA-X. We report the in-silico identification of novel isoforms of PB1-F2 and PA-X in influenza virus genomes sequenced from avian samples. The isoform observed in PA-X includes a mutated stop codon that should extend the protein product by 8 amino acids. The isoform observed in PB1-F2 includes two nonsense mutations that should truncate the N-terminal region of the protein product and remove the entire mitochondrial targeting domain. Both isoforms were uncovered during automatic annotation of CEIRS sequence data. Nominally termed PA-X8 and PB1-F2-Cterm, both predicted isoforms were subsequently found in other annotated influenza genomes previously deposited in GenBank. Both isoforms were noticed due to discrepant annotations output by two annotation engines, indicating a benefit of incorporating multiple algorithms during gene annotation.Antibiotic resistance is an increasing global problem and therapeutic alternatives to traditional antibiotics are needed. Antimicrobial and host defense peptides represent an attractive source for new therapeutic strategies, given their wide range of activities including antimicrobial, antitumoral and immunomodulatory. Insects produce several families of these peptides, including cecropins. 3-Amino-9-ethylcarbazole cost Herein, we characterized the sequence, structure, and biological activity of three cecropins called satanin 1, 2, and curvicin, found in the transcriptome of two dung beetle species Dichotomius satanas and Onthophagus curvicornis. Sequence and circular dichroism analyses show that they have typical features of the cecropin family short length (38-39 amino acids), positive charge, and amphipathic α-helical structure. They are active mainly against Gram-negative bacteria (3.12-12.5 μg/mL), with low toxicity on eukaryotic cells resulting in high therapeutic indexes (TI > 30). Peptides also showed effects on TNFα production in LPS-stimulated PBMCs. The biological activity of Satanin 1, 2 and Curvicin makes them interesting leads for antimicrobial strategies.

Ghrelin is a gut hormone with numerous physiological effects, including the regulation of energy balance, insulin sensitivity, vascular health, and body composition. Acylated (AG) and des-acylated (DAG) ghrelin constitute approximately 22 % and 78 % of total plasma ghrelin (TG), respectively. Alterations in the TG concentration and the AG/DAG ratio may be implicated in conditions involving energy imbalances and insulin resistant states (e.g., metabolic syndrome or Type 2 diabetes mellitus). Exercise is a therapeutic option that can potentially optimize ghrelin levels. Understanding the precise intensity and dose of exercise to optimize ghrelin levels may lead to targeted interventions to restore metabolic regulation in obesity and other clinical conditions.

To perform a systematic review and meta-analysis on the effects of acute exercise on pre-prandial levels of TG, AG, and DAG in healthy adults and to determine if sample demographics or exercise doses moderate such effects.

Electronic databases (PubMed, Medline, SPORTDiscus, Web of Science, and Google Scholar) were searched with articles published through August 2020.
