Evaluation of thin-threaded implants primary stability in type IV bone right after maxillary sinus floor elevation: A human cadaver study.

Purpose: The bone-implant interface plays a crucial role in obtaining sufficient primary stability for dental implants in weak bone supports. The aim of this human cadaver study was to evaluate the primary stability of new thin-threaded implants when placed in type IV bone right after maxillary sinus floor elevation.

Materials And Methods: The study followed the CACTUS (ChAracteristics of Cadaver Training and sUrgical Studies) guidelines.

Impaired Bone Tissue Quality Associated with Inflammation in HIV-Immunological Non-Responders: A Cross-Sectional Analysis.

Introduction: People with HIV (PWH) with poor immune response despite adequate antiretroviral treatment (ART) are susceptible to non-AIDS-related health issues. This study seeks to evaluate bone quality in Immunological Non-Responders (INRs) in comparison to those with proper immune response (IRs) using in vivo microindentation to quantify bone quality, in addition to conventional bone mineral density (BMD) evaluations.

Methods: A cross-sectional study was conducted at Hospital del Mar in Barcelona from January 2019 to June 2023.

Comparison of Camera-Acquired Vital Signs to Conventional Vital Signs in a Space-Analog Environment.

Introduction: Vital sign acquisition is a key component of modern medical care. In wilderness and space medical settings, vital sign acquisition can be a difficult process because of limitations on available personnel or lack of access to the patient. Camera-acquired vital signs could address each of these difficulties.

Beta-Hydroxybutyric Acid as a Template for the X-ray Powder Diffraction Analysis of Gamma-Hydroxybutyric Acid.

In this paper, we report the possibility of using the X-ray powder diffraction (XRPD) technique to detect gamma-hydroxybutyric acid (GHB) in the form of its sodium salt in different beverages, but because it is not possible to freely buy GHB, beta-hydroxybutyric acid (BHB) and its sodium salt (NaBHB) were used as a model to fine-tune an X-ray diffraction method for the qualitative analysis of the sodium salt of GHB. The method requires only a small quantity of beverage and an easy sample preparation that consists only of the addition of NaOH to the drink and a subsequent drying step. The dry residue obtained can be easily analyzed with XRPD using a single-crystal X-ray diffractometer, which exploits its high sensitivity and allows for very fast pattern collection.

Cell-Type-Specific Expression of Leptin Receptors in the Mouse Forebrain.

Leptin is a hormone produced by the small intestines and adipose tissue that promotes feelings of satiety. Leptin receptors (LepRs) are highly expressed in the hypothalamus, enabling central neural control of hunger. Interestingly, LepRs are also expressed in several other regions of the body and brain, notably in the cerebral cortex and hippocampus.
