Spectral Emissivity and Thermal Conductivity Properties of Black Aluminum Films.

Black aluminum is a material characterized by high surface porosity due to columnar growth and exhibits unique optical properties that make it attractive for applications such as light trapping, infrared detection, and passive thermal radiation cooling. In this study, we correlate the structural and optical properties of black aluminum by comparing it with conventional reflective aluminum layers. These layers of varying thicknesses were deposited on fused silica substrates, and their optical properties were analyzed.

Assessment of the level of knowledge on cervical cancer prevention among women visiting a private gynecological practice in Krakow - a pilot study.

Background: In 2022, more than 650,000 new cases of cervical cancer and more than 340,000 deaths were registered worldwide. Poland has some of the highest incidence and mortality rates from cervical cancer in Europe, despite the Cervical Cancer Prevention Program implemented for many years. Nowadays, with more information available, women should not die from cervical cancer (CC).

Microstructure and physical properties of black-aluminum antireflective films.

The microstructure and physical properties of reflective and black aluminum were compared for layers of different thicknesses deposited by magnetron sputtering on fused silica substrates. Reflective Al layers followed the Volmer-Weber growth mechanism classically observed for polycrystalline metal films. On the contrary, the extra nitrogen gas used to deposit the black aluminum layers modified the growth mechanism and changed the film morphologies.

Preoperative urine culture with contaminants is not associated with increased risk for urinary tract infection after ureteroscopic stone treatment.

Purpose: We aimed to assess whether the presence of contaminants in the pre-operative urine culture (preop-UC) predicts postoperative urinary tract infection (postop-UTI) in patients undergoing elective ureteroscopy with laser lithotripsy.

Methods: A retrospective chart review was performed from 01/2019 to 12/2021 examining patients with unilateral stone burden ≤ 2 cm who underwent ureteroscopy with laser lithotripsy and had a preop-UC within 3 months. Positive, negative, contaminated, and polymicrobial definitions for UCs were established in accordance with current guidelines.

Impact of Renal Access Angle and Speed of Nephroscope Retrieval Movements on the Vortex Effect.

Objective: To analyze the influence of different renal access angles (AAs) and nephroscope retrieval speeds on the efficacy of the vortex effect (VE) in mini-percutaneous nephrolithotomy (mini-PCNL). This study aimed to understand the poorly understood physical components of the VE.

Materials And Methods: A Pexiglas™ (KUS®) model was built based on the dimensions of a 15/16 F mini-PCNL set (Karl Storz).

Mental health conditions and help-seeking among Ukrainian war refugees in Czechia: A cross-sectional study.

Background: We aimed to screen Ukrainian war refugees (UWR) in Czechia for depression and anxiety, and to assess their recognition of personal mental health problems and related help-seeking.

Methods: We conducted a cross-sectional study on a sample of UWR in Czechia. We used PHQ-8 and GAD-7 to screen for depression and anxiety, SELF-I to assess the recognition of respondents' own mental health problems, and a set of questions regarding mental health-related help-seeking.

The Vortex Effect in Minimally Invasive Percutaneous Nephrolithotomy.

Objective: To describe the physical principles of the vortex effect to better understand its applicability in minimally invasive percutaneous nephrolithotomy (MIP) procedures.

Methods: Two acrylic phantom models were built based on the cross-sectional area (CSA) ratio of a MIP nephroscope and access sheaths (15/16F and 21/22F MIP-M, Karl Storz). The nephroscope phantom was 10 mm in diameter.

Optimizing stone harvesting in miniaturized-PCNL: a critical examination of renal access angles, technology, and the role they play in operative efficiency.

Purpose: Stone retrieval can be a laborious aspect of percutaneous nephrolithotomy (PCNL). A unique phenomenon of mini-PCNL is the vortex-effect (VE), a hydrodynamic form of stone retrieval. Additionally, the vacuum-assisted sheath (VAS) was recently developed as a new tool for stone extraction.

Surface Enhancement Using Black Coatings for Sensor Applications.

The resolution of a quartz crystal microbalance (QCM) is particularly crucial for gas sensor applications where low concentrations are detected. This resolution can be improved by increasing the effective surface of QCM electrodes and, thereby, enhancing their sensitivity. For this purpose, various researchers have investigated the use of micro-structured materials with promising results.

Efficacy of Norway Spruce Ointments and Bacterial and Fungal Alterations in the Treatment of Castration Wounds in Piglets.

This study aimed to evaluate the efficacy of Norway spruce ointments on wound healing of castration wounds in piglets. This study included 95 male pigs randomly divided into five treatment groups: Norway spruce balm (Vulpuran), Norway spruce resin (Abilar), pork lard (ointment base of Vulpuran), no treatment (negative control) and antibiotic blue spray (Cyclo spray, positive control). Wound healing parameters (such as healing time, wound size, reddening of wound edges and surrounding, swelling, secretion and wound contamination), microbiological status and the haptoglobin level as an inflammation parameter were investigated.

Activation of developmental nuclear fibroblast growth factor receptor 1 signaling and neurogenesis in adult brain by α7 nicotinic receptor agonist.

Reactivation of endogenous neurogenesis in the adult brain or spinal cord holds the key for treatment of central nervous system injuries and neurodegenerative disorders, which are major health care issues for the world's aging population. We have previously shown that activation of developmental integrative nuclear fibroblast growth factor receptor 1 (FGFR1) signaling (INFS), via gene transfection, reactivates neurogenesis in the adult brain by promoting neuronal differentiation of brain neural stem/progenitor cells (NS/PCs). In the present study, we report that targeting the α7 nicotinic acetylcholine receptors (α7nAChRs) with a specific TC-7020 agonist led to a robust accumulation of endogenous FGFR1 in the cell nucleus.

Schizophrenia: a neurodevelopmental disorder--integrative genomic hypothesis and therapeutic implications from a transgenic mouse model.

Schizophrenia is a neurodevelopmental disorder featuring complex aberrations in the structure, wiring, and chemistry of multiple neuronal systems. The abnormal developmental trajectory of the brain appears to be established during gestation, long before clinical symptoms of the disease appear in early adult life. Many genes are associated with schizophrenia, however, altered expression of no one gene has been shown to be present in a majority of schizophrenia patients.

Phosphorus removal from soy protein wastewater using novel crystallisation technology.

The objective of this work was to identify and implement a treatment method that would reduce the phosphorus (P) content of soy protein isolate manufacturing wastewater to an average of 2 mg L(-1) total P without increasing soluble salts in order to comply with discharge and receiving-water requirements. A novel crystallisation technology was evaluated through pilot studies that demonstrated these objectives could be met. Rapid settling (3.

Phosphorus removal using novel crystallisation technology.

A soy protein manufacturing facility was faced with the challenge of reducing its effluent phosphorus (P) content from 20-50 mg L(-1) down to <2 mg L(-1) total P without increasing soluble salt levels to comply with discharge and receiving water requirements. A number of biological and chemical P removal technologies previously evaluated either failed to achieve the new standards or would have produced prohibitive amounts of residual sludge and unacceptably high effluent salt concentrations. Lime precipitation, utilising a novel crystallisation technology, was demonstrated through on-site pilot testing to meet the process objectives.

[Clinical significance of the level of circulating immune complexes in patients with small cell bronchial carcinoma].

In the sera of 58 bronchial cancer patients with different TNM progression stage the relative 125I-C1q binding activities (BA) were determined before, after an induction of polychemotherapy and after a simultaneous polychemo- plus X-rays therapy. Only a statistically non-significant decrease of the 125I-C1q-BA was measured in the sera of patient groups with a stronger metastatic spread in the regional lymph nodes or distant metastasis. The tumor therapy cycles changed the serum 125I-C1q-BA differently and non significantly.
