EVALUATION OF PATIENTS WITH COVID-19 IN THE EARLY HYPOXEMIC STAGE AND PATIENTS WITH VIRAL RESPIRATORY TRACT INFECTION IN TERMS OF PULMONARY HYPERTENSION.

Arterial hypoxemia occurs in many COVID-19 patients. Hypoxemia is one of the causes of pulmonary hypertension (PH). Main pulmonary artery dilatation and the main pulmonary artery diameter (mPAD) to ascending aorta diameter (AAD) ratio of ≥1 are significant findings regarding PH.

Synergistic Effects of PARP Inhibition and Cholesterol Biosynthesis Pathway Modulation.

Unlabelled: An in-depth multiomic molecular characterization of PARP inhibitors revealed a distinct poly-pharmacology of niraparib (Zejula) mediated by its interaction with lanosterol synthase (LSS), which is not observed with other PARP inhibitors. Niraparib, in a similar way to the LSS inhibitor Ro-48-8071, induced activation of the 24,25-epoxysterol shunt pathway, which is a regulatory signaling branch of the cholesterol biosynthesis pathway. Interestingly, the combination of an LSS inhibitor with a PARP inhibitor that does not bind to LSS, such as olaparib, had an additive effect on killing cancer cells to levels comparable with niraparib as a single agent.

The relationship between optic disc-foveal distance with choroidal and retinal nerve fiber thickness.

Background: The optic disc-foveal distance is very important as it is an anatomical measure of the fundus. As this distance increases and the fundus tension, there may be variability in retinal and choroidal thickness. The aim of this study was to determine the relationship between optic disc-foveal distance and choroidal and retinal nerve fiber thickness in healthy subjects.

The relationship between sphenoidal sinus and sella turcica morphometry in the Turkish population: a retrospective study.

Purpose: The anatomical position of the sphenoidal sinus (SS) is very important for neurosurgeons because of the transsphenoidal approach to the pituitary gland. Therefore, the aim of this study was to determine the volume and shape of the SS and its relationship with the morphometry of the sella turcica.

Methods: This study included CT images of 282 males and 258 females with a mean age of 50.

Effects of Naphthoquinones from the Roots of Onosma Armeniacum Klokov on Wound Healing.

In Turkish folk medicine, the roots of Onosma armeniacum Klokov are used to heal wounds, burns, hemorrhoids, hoarseness, dyspnea, stomach ulcers, and abdominal aches. The objective was to evaluate the plant's ethnopharmacological applications using in vivo pharmacological experimental models. In vivo linear incision and circular excision the wound models were used to assess the wound healing activity along with histopathological investigation.
