Short-term results of unroofing and marsupialization compared to the Karydakis technique in the treatment of pilonidal sinus. A randomized prospective study.

Introduction: The treatment of pilonidal sinus (PS) is usually surgical, but no procedure is considered the gold standard. The Karydakis (K) technique is widely used, and unroofing and marsupialization (UM) is a simple surgery with good results.

Primary Objective: To evaluate early postoperative complications (EPC) 30 days after UM surgery compared to the K technique.

Deciphering Chemical Rules for Drug Penetration into Strongyloides.

Strongyloidiasis, a parasitic infection, presents a significant public health challenge in tropical regions due to the limited repertoire of effective treatments. The screening of chemical libraries against the therapeutically relevant third-stage larvae (L3) of the model parasite yielded meager success rates. This situation is reminiscent of Gram-negative bacteria, where drug entry is a limiting factor.

Experimental structure based drug design (SBDD) applications for anti-leishmanial drugs: A paradigm shift?

Leishmaniasis is a group of neglected tropical diseases caused by at least 20 species of Leishmania protozoa, which are spread by the bite of infected sandflies. There are three main forms of the disease: cutaneous leishmaniasis (CL, the most common), visceral leishmaniasis (VL, also known as kala-azar, the most serious), and mucocutaneous leishmaniasis. One billion people live in areas endemic to leishmaniasis, with an annual estimation of 30,000 new cases of VL and more than 1 million of CL.

Motor Activity-Induced White Matter Repair in White Matter Stroke.

Subcortical white matter stroke (WMS) is a progressive disorder which is demarcated by the formation of small ischemic lesions along white matter tracts in the CNS. As lesions accumulate, patients begin to experience severe motor and cognitive decline. Despite its high rate of incidence in the human population, our understanding of the cause and outcome of WMS is extremely limited.

Selective loss of CD107a TIGIT+ memory HIV-1-specific CD8+ T cells in PLWH over a decade of ART.

The co-expression of inhibitory receptors (IRs) is a hallmark of CD8+ T-cell exhaustion (Tex) in people living with HIV-1 (PLWH). Understanding alterations of IRs expression in PLWH on long-term antiretroviral treatment (ART) remains elusive but is critical to overcoming CD8+ Tex and designing novel HIV-1 cure immunotherapies. To address this, we combine high-dimensional supervised and unsupervised analysis of IRs concomitant with functional markers across the CD8+ T-cell landscape on 24 PLWH over a decade on ART.

Subcortical White Matter Stroke in the Mouse: Inducing Injury and Tracking Cellular Proliferation.

Here, we describe a method for inducing subcortical white matter stroke in mice, as well as tracking cellular proliferation through drinking water administration of EdU and ex vivo labeling.

Different Brain Phenotypes in Magnetic Resonance Imaging of Healthy Children after Prenatal Insults.

In this study, we used magnetic resonance imaging (MRI) to identify the different brain phenotypes within apparently healthy children and to evaluate whether these phenotypes had different prenatal characteristics. We included 65 healthy children (mean age, 10 years old) with normal neurological examinations and without structural abnormalities. We performed cluster analyses to identify the different brain phenotypes in the brain MRI images.

Monitoring of Circulating Tumor DNA Predicts Response to Treatment and Early Progression in Follicular Lymphoma: Results of a Prospective Pilot Study.

Purpose: Follicular lymphoma (FL) is the most frequent indolent non-Hodgkin lymphoma. Around 20% of patients suffer early disease progression within 24 months (POD24) of diagnosis. This study examined the significance of circulating tumor DNA (ctDNA) in predicting response to therapy and POD24 in patients with FL.

Total en bloc spondylectomy for the L5 metastasis of a carcinoid tumor: illustrative case.

Background: Total en bloc spondylectomy (TES) was designed to achieve oncological complete tumor resection in a vertebral compartment. Because of the special anatomy of the lumbosacral junction, TES procedure at the L5 level is a challenge, and it has been explained in few reports in the literature. Performing TES in the lower lumbar region, as normal, is accomplished by using a combined approach.

The Masked Polar Group Incorporation (MPGI) Strategy in Drug Design: Effects of Nitrogen Substitutions on Combretastatin and Isocombretastatin Tubulin Inhibitors.

Colchicine site ligands suffer from low aqueous solubility due to the highly hydrophobic nature of the binding site. A new strategy for increasing molecular polarity without exposing polar groups-termed masked polar group incorporation (MPGI)-was devised and applied to nitrogenated combretastatin analogues. Bulky substituents to the pyridine nitrogen hinder it from the hydrophobic pocket while increasing molecular polarity.

Contribution of apical and basal dendrites to orientation encoding in mouse V1 L2/3 pyramidal neurons.

Pyramidal neurons integrate synaptic inputs from basal and apical dendrites to generate stimulus-specific responses. It has been proposed that feed-forward inputs to basal dendrites drive a neuron's stimulus preference, while feedback inputs to apical dendrites sharpen selectivity. However, how a neuron's dendritic domains relate to its functional selectivity has not been demonstrated experimentally.

White Matter Stroke Induces a Unique Oligo-Astrocyte Niche That Inhibits Recovery.

Subcortical white matter stroke is a common stroke subtype. White matter stroke stimulates adjacent oligodendrocyte progenitor cells (OPCs) to divide and migrate to the lesion, but stroke OPCs have only a limited differentiation into mature oligodendrocytes. To understand the molecular systems that are active in OPC responses in white matter stroke, OPCs were virally labeled and laser-captured in the region of partial damage adjacent to the infarct in male mice.

Multistate Models: Accurate and Dynamic Methods to Improve Predictions of Thrombotic Risk in Patients with Cancer.

Research into cancer-associated thrombosis (CAT) entails managing dynamic data that pose an analytical challenge. Thus, methods that assume proportional hazards to investigate prognosis entail a risk of misinterpreting or overlooking key traits or time-varying effects. We examined the AGAMENON registry, which collects data from 2,129 patients with advanced gastric cancer.

Treatment in esophagogastric junction cancer: Past, present and future.

Adenocarcinomas of the gastroesophageal junction represent 27% of all gastric tumors. n recent years, it has been classified as an entity of its own, with specific treatments that are sometimes differentiated from gastric treatments. Treatment can be based on chemotherapy (CTx) or chemoradiotherapy (CRTx) that is administered preoperatively (neoadjuvant), postoperatively (adjuvant) or perioperatively.

Duration of immunity to measles, rubella and mumps during the first year of life.

Introduction And Objectives: The MMR vaccine was included in the official vaccination schedule in Spain in 1981. Currently, most women of childbearing age are vaccinated and have not been naturally infected. Several studies have shown that vaccinated women have a lower antibody concentration than that achieved after natural infection, and a shorter duration of transplacentally acquired antibodies in their children.

Is prophylactic gastrectomy indicated for healthy carriers of CDH1 gene mutations associated with hereditary diffuse gastric cancer?

Introduction: hereditary diffuse gastric cancer (HDGC) is a recently reported hereditary cancer syndrome. Patients with suspected HDGC must be under surveillance via endoscopy and multiple biopsies. As an alternative, some studies suggest prophylactic gastrectomy (PG) for disease carriers.

Bioselection Reveals miR-99b and miR-485 as Enhancers of Adenoviral Oncolysis in Pancreatic Cancer.

Oncolytic viruses are designed for cancer treatment. Cell-virus interactions are key determinants for successful viral replication. Therefore, the extensive reprogramming of gene expression that occurs in tumor cells might create a hurdle for viral propagation.

Stroke in CNS white matter: Models and mechanisms.

White matter stroke (WMS) is a debilitating disorder, which is characterized by the formation of ischemic lesions along subcortical white matter tracts of the central nervous system. Initial infarction during the early stages of the disease is often asymptomatic and is thus considered a form of silent stroke. However, over time lesions accumulate, resulting in severe cognitive and motor decline of which there are no known therapies.

Mechanisms of demyelination and remyelination in the young and aged brain following white matter stroke.

Subcortical white matter stroke (WMS) accounts for 25% of all incidences of stroke and results in severe motor and cognitive disability. WMS stands as the second leading cause of dementia and is immensely prevalent in older adults. In a startlingly statistic, a majority of human beings will present WMS by 80 years of age.
