Micelles of poly[oligo(ethylene glycol) methacrylate] as delivery vehicles for zinc phthalocyanine photosensitizers.

Drug-loaded polymeric micelles have proven to be highly effective carrier systems for the efficient delivery of hydrophobic photosensitizers (PSs) in photodynamic therapy (PDT). This study introduces the micellization potential of poly(oligoethylene glycol methyl ether methacrylate) (pOEGMA) as a novel approach, utilizing the hydrophobic methacrylate segments of pOEGMA to interact with highly hydrophobic zinc phthalocyanine (ZnPc), thereby forming a potential micellar drug carrier system. The ZnPc molecule was synthesized from phthalonitrile derivatives and its fluorescence, photodegradation, and singlet oxygen quantum yields were determined in various solvents.

Noncoding RNAs in apoptosis: identification and function.

Apoptosis is a vital cellular process that is critical for the maintenance of homeostasis in health and disease. The derailment of apoptotic mechanisms has severe consequences such as abnormal development, cancer, and neurodegenerative diseases. Thus, there exist complex regulatory mechanisms in eukaryotes to preserve the balance between cell growth and cell death.

Anxiety and depression in the first 24 h in COVID-19 patients who underwent non-invasive mechanical ventilation in the intensive care unit.

Background And Aims: The aim of this study was to investigate the degree of anxiety and depression in the first 24 h of people who were taken to the intensive care unit (ICU) due to COVID-19 and had to use unfamiliar devices in an unfamiliar environment.

Material Method: Sixty-two patients over 18 years of age, conscious and cooperative, who were admitted to the ICU with the diagnosis of COVID, were PCR (+), and needed non-invasive mechanical ventilation were included in the study. Age, gender, Acute Physiology and Chronic Health Evaluation (APACHE) II scores, and Hospital Anxiety Depression (HAD) A (anxiety), and HAD D (depression) scores of the patients were recorded, and the prevalence of anxiety and depression and independent factors affecting them were investigated.

Preoperative proteinuria is associated with increased rates of acute kidney injury after partial nephrectomy.

Purpose: We investigated the association between preoperative proteinuria and early postoperative renal function after robotic partial nephrectomy (RPN).

Patients And Methods: We retrospectively reviewed 1121 consecutive RPN cases at a single academic center from 2006 to 2016. Patients without pre-existing CKD (eGFR≥60 mL/min/1.

Risk assessment of PBDEs and PAHs in house dust in Kocaeli, Turkey: levels and sources.

Indoor dust samples were collected from 40 homes in Kocaeli, Turkey and were analyzed simultaneously for 14 polybrominated diphenyl ethers (PBDEs) and 16 poly aromatic hydrocarbons (PAHs) isomers. The total concentrations of PBDEs (ΣPBDEs) ranged from 29.32 to 4790 ng g, with a median of 316.

Simultaneous occurrence of metabolic, hematologic, neurologic and cardiac complications after Roux-en-Y gastric bypass for morbid obesity.

Roux-en-Y gastric bypass (RYGB) is a commonly performed procedure in the surgical treatment of morbid obesity. Since a major anatomical alteration is made, this procedure may lead to significant postoperative complications, including nutritional deficiencies related to malabsorption. As a consequence of micronutrient deficiencies, secondary metabolic, hematologic and neurologic complications might also develop.

Phenacyl Ethyl Carbazolium as a Long Wavelength Photoinitiator for Free Radical Polymerization.

A new phenacyl-type photoinitiator based on ethyl carbazole as a long wavelength photo-initiator is developed for free radical polymerization. Phenacyl ethyl carbazolium hexafluoroantimonate (PECH) photoinitiator is synthesized in a two-step, one-pot manner by quaternizing ethyl carbazole with phenacyl bromide and subsequent ion exchange reaction with potassium hexafluoroantimonate. Under irradiation, PECH tends to undergo homolytic bond cleavage bringing about initiating free radicals.
