The multiscale topological organization of the functional brain network in adolescent PTSD.

The experience of an extremely aversive event can produce enduring deleterious behavioral, and neural consequences, among which posttraumatic stress disorder (PTSD) is a representative example. Although adolescence is a period of great exposure to potentially traumatic events, the effects of trauma during adolescence remain understudied in clinical neuroscience. In this exploratory work, we aim to study the whole-cortex functional organization of 14 adolescents with PTSD using a data-driven method tailored to our population of interest.

Review of Explosive Contamination and Bioremediation: Insights from Microbial and Bio-Omic Approaches.

Soil pollution by TNT(2,4,6-trinitrotoluene), RDX(hexahydro-1,3,5-trinitro-1,3,5-triazacyclohexane), and HMX(octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), resulting from the use of explosives, poses significant challenges, leading to adverse effects such as toxicity and alteration of microbial communities. Consequently, there is a growing need for effective bioremediation strategies to mitigate this damage. This review focuses on Microbial and Bio-omics perspectives within the realm of soil pollution caused by explosive compounds.

Forehead Reduction Surgery with Hairline Advancement.

Hairline reduction surgery, also known as aesthetic forehead reduction, is a surgical procedure that aims to reduce the upper facial third and improve facial harmony. This article describes the anatomy of hairline advancement surgery and the surgical technique used by the author. The study included 21 patients from 2019 to 2023, and the forehead reduction length was on average 22.

[The dynamic brain-network model of PTSD].

The brain is a highly complex system whose functioning is critical for our interaction with the world. Neural elements, from single cells to brain systems, constantly fluctuate in their dynamics, accompanying the plethora of possible exchanges between our environment and ourselves. However, sometimes things go awry.

Results of Preimplantation Genetic Testing for Aneuploidy (PGT-A) in a Cohort of 319 Embryos: Experience in a Fertility Clinic in Colombia.

Objective: To analyze the results of the preimplantation genetic testing for aneuploidy at the Instituto de Fertilidad Humana - Inser Bogotá, Colombia, from 2016 to 2020.

Methods: This study is an observational, retrospective, and correlative analysis of biopsies from 319 embryos (from 54 patients) submitted to preimplantation genetic testing for aneuploidy by different molecular techniques.

Results: Of the 54 patients included in the study, 42 provided their own oocytes, and 12 used donated oocytes.

Normalization of vital signs does not reduce the probability of acute pulmonary embolism in symptomatic emergency department patients.

Objectives: In a patient with symptoms of pulmonary embolism (PE), the presence of an elevated pulse, respiratory rate, shock index, or decreased pulse oximetry increases pretest probability of PE. The objective of this study was to evaluate if normalization of an initially abnormal vital sign can be used as evidence to lower the suspicion for PE.

Methods: This was a prospective, noninterventional, single-center study of diagnostic accuracy conducted on adults presenting to an academic emergency department (ED), with at least one predefined symptom or sign of PE and one risk factor for PE.

Evaluation and characterization of forage Sorghum as feedstock for fermentable sugar production.

Sorghum is a tropical grass grown primarily in semiarid and drier parts of the world, especially areas too dry for corn. Sorghum production also leaves about 58 million tons of by-products composed mainly of cellulose, hemicellulose, and lignin. The low lignin content of some forage sorghums such as brown midrib makes them more digestible for ethanol production.

Genetic variability among populations of Lutzomyia (Psathyromyia) shannoni (Dyar 1929) (Diptera: Psychodidae: Phlebotominae) in Colombia.

Polyacrylamide gel electrophoresis was used to elucidate genetic variation at 13 isozyme loci among forest populations of Lutzomyia shannoni from three widely separated locations in Colombia: Palambí (Nariño Department), Cimitarra (Santander Department) and Chinácota (Norte de Santander Department). These samples were compared with a laboratory colony originating from the Magdalena Valley in Central Colombia. The mean heterozygosity ranged from 16 to 22%, with 2.

Reproductive biology of Lutzomyia shannoni (Dyar) (Diptera: Psychodidae) under experimental conditions.

Baseline biological growth data of Lutzomyia shannoni (Dyar) were compared under two experimental conditions within insulated styrofoam chests and in standard laboratory incubators. The developmental time from egg to adult was 67 and 52 days, respectively. Based on cohorts of 100 females in each experiment, horizontal life tables were constructed.

Life cycle and fecundity analysis of Lutzomyia shannoni (Dyar) (Diptera: Psychodidae).

The life cycle of Lutzomyia shannoni (Dyar), was described for laboratory conditions with maximum daily temperature of 27-30 degree C, minimum daily temperatures of 22-27 degree C and relative humidity between 87-99%. Life cycle in each stage was as follows: egg 6-12 days (ave, 8.5 days); first stage larva 5-13 days (ave.
