Cardiovascular diseases (CVDs) are the leading global cause of mortality and disease burden. statins are the most prescribed lipid-lowering drugs to treat hypercholesterolemia and prevent CVDs. The biochemical mechanism of statins consists of competitive inhibition of the 3-hydroxy-3-methylglutaryl-CoA reductase enzyme (HMG-CoAR)， the limiting enzyme in cholesterol biosynthesis. Due to statin intolerance in some patient groups， the search for new inhibitors is a field of great interest. This review focusses on the studies reporting the inhibitory effect of protein hydrolysates and biopeptides on the HMG-CoAR enzyme activity. The analysis of the action mechanism and physicochemical characteristics of the HMG-CoAR inhibitory peptides revealed that the molecular weight， amino acid composition， charge， and polarity are key aspects of the interaction with the HMG-CoAR enzyme. In conclusion， this review reveals the potential of using food peptides as new cholesterol-lowering agents and opens a new interesting field of research. However， clinical approaches are mandatory to confirm their therapeutic hypercholesterolemic effect.

This study presents an analysis of sediments in an Andean river impacted by both natural conditions and anthropogenic activities. Fifty samples were collected from selected sites throughout the Moquegua River drainage basin, and Tambo River headwaters at Pasto Grande, in Peru, and analysed with X-ray diffraction, energy dispersive X-ray spectroscopy, scanning electron microscopy, Fourier-transform infrared spectroscopy and thermogravimetric analysis. si, Ca, Al, Fe, and O, common constituents of soils, were dominant, along with K, N, and P. The latter originating as primary macronutrients or chemical residuals from fertilizers used in agriculture. Higher concentrations of macronutrients and organic components were found in agricultural and urban areas, respectively. Arsenic minerals were also detected, which occur naturally, but possibly at levels augmented by anthropogenic activity. The application of cluster analysis revealed clustering between arsenic, arsenolite, and potassium but no significant geospatial correlation between sample sites in the drainage basin.

Objective: To compare the presence of Mycoplasma spp. in pharyngeal swabs of patients with asthma, allergic rhinitis and controls, also to compare the reactivity to allergens in the three groups. Material and Methods: Throat swabs of 120 patients with asthma, 211 allergic rhinitis patients and 171 healthy persons were cultured in E media. Positive cultures were identified by PCR. susceptibility of patients positive for isolation of Mycoplasma spp. to indoor, forest and undergrowth allergens were determined. Results: Mycoplasma spp. was isolated in 26.6% of samples from asthmatic patients, 36% in patients with allergic rhinitis and 2.9% in the group of healthy persons. Positive patients for Mycoplasma with asthma and allergic rhinitis showed susceptibility tomite, grass and thunder mainly. Conclusion: There is a higher incidence of Mycoplasma spp. in asthmatic and allergic rhinitis patients than healthy persons. Only patients with asthma or allergic rhinitis showed reactivity to environmental allergens.

The leaf-response to three-soil applied treatments of Paclobutrazol (PBZ;1000, 2000 and 0 ppm-control) was studied in a high-density plantation of eight guava (Psidium guajava) genotypes trees. All materials were prunned in vase form, with two to three major branches, yearly prunning for triggering the annual production cycle, and average height of 2.0 m. The dataset comprises fourth radiometric indices highly related to plant physiological activities. The dataset model took into account data collection dates, guava genotypes, and the positional effect of sun radiation on leaves based on their proximity to the canopy level and downward to the base of the woody seasonal-branch. Unexpectedly, there were no significant differences (Ns) in PBZ treatments for genotypes, leaf position and radiometric indices. Analysis of the radiometric indices data revealed that anthocyanin (ARI index) and chlorophyll (PRI index) have a strong inverse relationship. significant differences (P ≤ 0.05) were found between guava genotypes, and anthocyanin content;these results show that guava genotypes have varied responses, which could derive in their classification based-on drought resistance or low water requirements, however, it is important to note that additional research is required to determine the scope of these indications.

style="text-align:justify;"> strong>Background:strong> Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.

AIM To investigated the real-world effectiveness and safety of various regimens of interferon-free treatments in patients infected with hepatitis C virus(HCV).METHODs We performed an observational study to analyze different antiviral treatments administered to 462 HCV-infected patients, of which 56.7% had liver cirrhosis. HCV RNA after 4 wk of treatment and at 12 wk after treatment sustained virologic response(sVR) as well as serious adverse events(sAEs) was analyzed first for the whole cohort and then separately in patients who met or did not meet the inclusion criteria of a clinical trial(CT-met and CT-unmet, respectively).REsULTs The most frequently prescribed treatment was simeprevir/sofosbuvir(36.4%), followed by sofosbuvir/ledipasvir(24.9%) and ombitasvir/paritaprevir/ritonavir(r)/dasabuvir(19.9%). Ribavirin(RBV) was administered in 198 patients(42.9%). sVRs occurred in 437/462 patients(94.6%). The sVRs ranged between 93.3% and 100% for genotypes 1-4. sVRs were achieved in 96.2% patients in the CTmet group vs 91.9% patients in the CT-unmet group(P = 0.049). Undetectable HCV RNA at week 4 occurred in 72.9% of the patients. In the univariate analysis, the factors associated with sVRs were lower liver stiffness, absence of cirrhosis, higher platelet count, higher albumin levels, no RBV dose reduction, undetectable HCV RNA at week 4 and CT-met group. In the multivariate analysis, only albumin was an independent predictor of treatment failure(P = 0.04). Eleven patients(2.4%) developed sAEs; 5.2% and 0.7% of the patients in the CT-unmet and CT-met groups, respectively(P = 0.003).CONCLUsION A high proportion of patients with HCV infection achieved sVRs. For patients who did not meet the CT criteria, treatment regimens must be optimized.
