Non-Coding RNAs and Innate Immune Responses in Cancer.

Non-coding RNAs (ncRNAs) and the innate immune system are closely related, acting as defense mechanisms and regulating gene expression and innate immunity. Both are modulators in the initiation, development and progression of cancer. We aimed to review the major types of ncRNAs, including small interfering RNAs (siRNAs), microRNAs (miRNAs), piwi-interacting RNAs (piRNAs), and long non-coding RNAs (lncRNAs), with a focus on cancer, innate immunity, and inflammation.

Targeting Neutrophil Extracellular Trap Formation: Exploring Promising Pharmacological Strategies for the Treatment of Preeclampsia.

Neutrophils, which constitute the most abundant leukocytes in human blood, emerge as crucial players in the induction of endothelial cell death and the modulation of endothelial cell responses under both physiological and pathological conditions. The hallmark of preeclampsia is endothelial dysfunction induced by systemic inflammation, in which neutrophils, particularly through the formation of neutrophil extracellular traps (NETs), play a pivotal role in the development and perpetuation of endothelial dysfunction and the hypertensive state. Considering the potential of numerous pharmaceutical agents to attenuate NET formation (NETosis) in preeclampsia, a comprehensive assessment of the extensively studied candidates becomes imperative.

Associations of Dynapenic Obesity and Sarcopenic Obesity with the Risk of Complications in COVID-19.

Ageing is associated with changes in body composition, such as low muscle mass (sarcopenia), decreased grip strength or physical function (dynapenia), and accumulation of fat mass. When the accumulation of fat mass synergistically accompanies low muscle mass or reduced grip strength, it results in sarcopenic obesity and dynapenic obesity, respectively. These types of obesity contribute to the increased risk of cardiovascular disease and mortality in the elderly, which could increase the damage caused by COVID-19.

Mechanisms of Immunothrombosis by SARS-CoV-2.

SARS-CoV-2 contains certain molecules that are related to the presence of immunothrombosis. Here, we review the pathogen and damage-associated molecular patterns. We also study the imbalance of different molecules participating in immunothrombosis, such as tissue factor, factors of the contact system, histones, and the role of cells, such as endothelial cells, platelets, and neutrophil extracellular traps.

Priapism as the first manifestation in chronic myeloid leukemia: A case report and focused review of literature.

We report the case of a patient who was initially presented with ischemic priapism to the emergency department. He was treated with adrenaline intracavernous injections and aspiration with irrigation of the corpora cavernosa and distal shunt. In the postoperative period, anemia, basophilia, eosinophilia, thrombocytosis and hyperleukocytosis were detected.

Interaction of Spike protein and lipid membrane of SARS-CoV-2 with Ursodeoxycholic acid, an in-silico analysis.

Numerous repositioned drugs have been sought to decrease the severity of SARS-CoV-2 infection. It is known that among its physicochemical properties, Ursodeoxycholic Acid (UDCA) has a reduction in surface tension and cholesterol solubilization, it has also been used to treat cholesterol gallstones and viral hepatitis. In this study, molecular docking was performed with the SARS-CoV-2 Spike protein and UDCA.

The influence of hydrogen ions on coagulation in traumatic brain injury, explored by molecular dynamics.

: Patients in intensive care units with traumatic brain injuries (TBI) frequently present acid-base abnormalities and coagulability disorders, which complicate their condition.: To identify protonation through simulations of molecules involved in the process of coagulation in standard laboratory tests.: Ten patients with TBI were selected from the intensive care unit in addition to ten "healthy control subjects", and another nine patients as "disease control subjects"; the latter being a comparative group, corresponding to subjects with diabetes mellitus 2 (DM2).

Molecules and Prostaglandins Related to Embryo Tolerance.

It is generally understood that the entry of semen into the female reproductive tract provokes molecular and cellular changes facilitating conception and pregnancy. We show a broader picture of the participation of prostaglandins in the fertilization, implantation and maintenance of the embryo. A large number of cells and molecules are related to signaling networks, which regulate tolerance to implantation and maintenance of the embryo and fetus.

Analysis of SARS-CoV-2 mutations in Mexico, Belize, and isolated regions of Guatemala and its implication in the diagnosis.

The genomic sequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) worldwide are publicly available and are derived from studies due to the increase in the number of cases. The importance of study of mutations is related to the possible virulence and diagnosis of SARS-CoV-2. To identify circulating mutations present in SARS-CoV-2 genomic sequences in Mexico, Belize, and Guatemala to find out if the same strain spread to the south, and analyze the specificity of the primers used for diagnosis in these samples.

Aggregation and Molecular Properties of β-Glucosidase Isoform II in Chayote ().

The presence of isoforms of β-glucosidase has been reported in some grasses such as sorghum, rice and maize. This work aims to extract and characterize isoform II in β-glucosidase from . A crude extract was prepared without buffer solution and adjusted to pH 4.

Safety and patients' satisfaction after hysteroscopic sterilisation.

The aim of this study was to understand the potential complications of the Essure device as well as the factors influencing its onset and patient satisfaction. We present a 9-year descriptive prospective study that included 1068 patients. The device was placed in 1056 of them (98.

[Ureteral lesions in gynecologic surgery].

Objectives: Ureteral lesions during gynaecologic surgery are a serious problem, affecting morbidity even when they are diagnosed postoperatively.

Methods: 742 gynaecological surgical procedures performed between 1994 and 2000 at the Manuel Fajardo University Hospital where evaluated. Eight operations were complicated with ureteral lesions (1.

A simple index for detection of gestational diabetes mellitus.

The conventional screening test for gestational diabetes mellitus is measurement of plasma glucose 1 hour after 50 g glucose by mouth. The sensitivity and specificity of this test are lower than desirable; we therefore developed an index including other plasma constituents. In a preliminary study, 138 pregnant women had the standard oral glucose load screening test, and plasma fructosamine and total proteins were measured, in addition to glucose, in the 1-hour samples.

[Spontaneous bleeding from renal cyst as a cause of acute anemia].

Objective: To report a case of a simple left renal cyst in a patient who presented with spontaneous pain and acute anemia due to intracystic hemorrhage.

Methods: Diagnostic imaging techniques such as assessment of the urinary tract with contract medium, ultrasound CT and MRI were utilized for correct preoperative diagnosis and surgical management.

Results: The patient was able to return to normal active work.
