Virtual screening of potential inhibitors of the ATPase site in Acinetobacter baumannii DNA Gyrase.

Bacterial resistance is a global public health problem because of the ineffectiveness of conventional antibiotics against super pathogens. To counter this situation, the search for or design of new molecules is essential to inhibit the key proteins involved in several stages of bacterial infection. One of these key proteins is DNA gyrase, which is responsible for packaging and unfolding of DNA chains during replication.

Effect of Mediterranean Diet in Combination with Isokinetic Exercise Therapy on Body Composition and Cytokine Profile in Patients with Metabolic Syndrome.

Background: Metabolic syndrome (MS) is a combination of comorbidities that increase pro-inflammatory cytokines (PIC) production, with subsequent body composition (BC) abnormalities and high cardiovascular risk. Treatment with diet and exercise has been suggested as possible non-pharmacological adjuvant treatment.

Objective: To determine changes in BC and PIC in patients with MS after a Mediterranean-type diet (MedDiet) and/or isokinetic exercise (IE).

Impact of Combined Thermo- and Photo-Oxidation on the Physicochemical Properties of Oxo-Biodegradable Low-Density Polyethylene Films.

This research addresses the study of the combined effect of two abiotic treatments, a thermo-oxidative treatment followed by a photo-oxidative treatment with ultraviolet light, on the physicochemical properties of commercially available low-density polyethylene films with an oxo-degradant additive (OXOLDPE) and without (LDPE). The change in the oxidized film properties was characterized using FTIR, XRD, TGA, GPC, and SEM analytical techniques. The results indicated that the increment in carbonyl index (CI) and crystallinity percentage (X) was higher for those films that received the combined oxidative treatments compared with those that received only one of them, thermo- or photo-oxidative treatment.

Antidepressant- and Anxiolytic-like Effects in Mice of Alkaloids from Aerial Parts of Link & Otto.

Link & Otto, an endemic plant of Mexico, is widely distributed in the central area of the country, mainly in the states of Tlaxcala, Puebla, and the State of Mexico. Ethnobotanical studies in different communities of these states have demonstrated that it is primarily used to treat diabetes and mental illnesses, such as "los nervios" (nerves) and "el ansia" (anxiety); these terms are used in traditional medicine, but it is accepted that they refer to anxiety disorders. This study aimed to validate the traditional use of aerial parts of Link & Otto in treating these illnesses.

Is It Feasible to Apply a Virtual Box and Block Test in Children with Unilateral Cerebral Palsy?: A Pilot Study.

: With technological advancements, virtual versions of the Box and Block Test (BBT) employing the Leap Motion Controller have been developed for evaluating hand dexterity. Currently, there are no studies about the usefulness of this system in children with unilateral cerebral palsy (UCP). Thus, our main objective is to apply a virtual BBT based on the Leap Motion Controller in children with UCP compared with the real BTT for assessing upper limb function within a pilot study.

Associations of Voice Metrics with Postural Function in Parkinson's Disease.

Background: This study aimed to explore the potential associations between voice metrics of patients with PD and their motor symptoms.

Methods: Motor and vocal data including the Unified Parkinson's Disease Rating Scale part III (UPDRS-III), Harmonic-Noise Ratio (HNR), jitter, shimmer, and smoothed cepstral peak prominence (CPPS) were analyzed through exploratory correlations followed by univariate linear regression analyses. We employed these four voice metrics as independent variables and the total and sub-scores of the UPDRS-III as dependent variables.

Sonochemical Functionalization of SiO Nanoparticles with Citric Acid and Monoethanolamine and Its Remarkable Effect on Antibacterial Activity.

Nanoparticles (NPs) are excellent antibacterial agents due to their ability to interact with microorganisms at the cellular level. However, their antimicrobial capacity can be limited by their tendency to agglomerate. Functionalizing NPs with suitable ligands improves their stability and dispersion in different media and enhances their antibacterial activity.

Decoding the Contribution of IAPP Amyloid Aggregation to Beta Cell Dysfunction: A Systematic Review and Epistemic Meta-Analysis of Type 1 Diabetes.

Diabetes Mellitus Type 1 (DM1) is an autoimmune disease characterized by the destruction of beta cells in the pancreas. Although amyloid formation has been well-studied in Diabetes Mellitus Type 2 (DM2), its role in DM1 remains unclear. Understanding how islet amyloid polypeptide (IAPP) contributes to beta cell dysfunction and death in DM1 could provide critical insights into disease mechanisms and pave the way for novel diagnostic and therapeutic strategies.

Comparative Analysis of Immune Response Genes Induced by a Virulent or Attenuated Strain of .

RNA-seq technology has been widely used for the characterization of the transcriptome profile induced by several diseases in both humans and animals. In the present study, RNA-seq was used to identify the differential expression of genes associated with the immune response in cattle infected with two different strains of , both derived from the same Mexican field isolate, which exhibit distinct phenotypic characteristics: the virulent strain, capable of producing acute clinical signs, and the attenuated strain, capable of stimulating a protective immune response when used as an immunogen with an efficacy greater than 80%. The differential gene expression analysis performed revealed a total of 620 differentially expressed genes (DEGs).

Our research highlights the pivotal role of OmpR, a key regulator within the EnvZ/OmpR two-component system, in controlling the virulence factors associated with .

Bactericidal/Permeability-Increasing Protein (BPI), a Novel Antimicrobial Molecule in Human Breast Milk with Immune Potential.

Breast milk is a fluid of vital importance during the first stages of life of the newborn since, in addition to providing nutrients, it also contains cells and molecules of the immune system, which protect the neonate from infection and, at the same time, modulate the establishment of the microbiota. Bactericidal/permeability-increasing protein (BPI) is relevant in preventing disease and sepsis in neonates. Therefore, the following work aimed to demonstrate the presence of BPI in the different stages of breast milk and its possible immune functions.

Cooperation Between and for Carbendazim Degradation.

Carbendazim (CBZ) is a fungicide widely used on different crops, including soybeans, cereals, cotton, tobacco, peanuts, and sugar beet. Excessive use of this xenobiotic causes environmental deterioration and affects human health. Microbial metabolism is one of the most efficient ways of carbendazim elimination.

iNOS-Produced Nitric Oxide from Cancer Cells as an Intermediate of Stemness Regulation by PARP-1 in Colorectal Cancer.

PARP-1 has been linked to the progression of several types of cancer. We have recently reported that PARP-1 influences tumor progression in CRC through the regulation of CSCs in a p53-dependent manner. In this study, we propose that nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) could act as a mediator.

Urinary Proteome and Exosome Analysis Protocol for the Discovery of Respiratory Diseases Biomarkers.

This study aims to develop a protocol for respiratory disease-associated biomarker discovery by combining urine proteome studies with urinary exosome components analysis (i.e., miRNAs).

The Metabolism of Creatinine and Its Usefulness to Evaluate Kidney Function and Body Composition in Clinical Practice.

Serum creatinine levels are the most used clinical marker to estimate renal function as the glomerular function rate because it is simple, fast, and inexpensive. However, creatinine has limitations, as its levels can be influenced by factors such as advanced age, physical activity, protein-rich diets, male gender, medications, and ethnicity. Serum cystatin C and its combination with serum creatinine may serve as an alternative since these factors do not affect it.
