Cleaning of Ultrafiltration Membranes: Long-Term Treatment of Car Wash Wastewater as a Case Study.

Car wash wastewaters (CWWs) contain various pollutants with different contents. Hence, selecting an appropriate process for their treatment is a great challenge. Undoubtedly, the ultrafiltration (UF) process is one of the most interesting and reliable choices.

Biogas Upgrading Using a Single-Membrane System: A Review.

In recent years, the use of biogas as a natural gas substitute has gained great attention. Typically, in addition to methane (CH), biogas contains carbon dioxide (CO), as well as small amounts of impurities, e.g.

Exploration of current pharmacy practice in cardio-oncology: Experiences & perspectives.

Introduction: Cardiovascular complications can occur in oncology patients secondary to certain cancer therapies. Pharmacists are involved in the care of oncology patients who are at risk of or experiencing cardiotoxicity related to their cancer therapy. Our study aimed to understand how pharmacists in Canada care to these patients and to explore their experiences, perceptions, and challenges.

Performance of 5-Strand Hamstring Autograft Anterior Cruciate Ligament Reconstruction in the STABILITY Study: A Subgroup Analysis.

Background: Anterior cruciate ligament (ACL) reconstructions (ACLRs) with graft diameters <8mm have been shown to have higher revision rates. The 5-strand (5S) hamstring autograft configuration is a proposed option to increase graft diameter.

Purpose: To investigate the differences in clinical outcomes between 4-strand (4S) and 5S hamstring autografts for ACLR in patients who underwent ACLR alone or concomitantly with a lateral extra-articular tenodesis (LET) procedure.

Prognostic value of lymph node ratio in resectable rectal cancer after preoperative short-course radiotherapy-results from randomized clinical trial.

Purpose: The value of the lymph node ratio (LNR) in patients with rectal cancer has not yet been unequivocally established. This study aims to assess the effect of the lymph node ratio on the prognosis of rectal cancer in patients operated after short-course preoperative 25 Gy radiotherapy, at 10-year follow-up.

Methods: This is a substudy based on data from a prospective randomized clinical trial.

Predictors of Graft Failure in Young Active Patients Undergoing Hamstring Autograft Anterior Cruciate Ligament Reconstruction With or Without a Lateral Extra-articular Tenodesis: The Stability Experience.

Background: Anterior cruciate ligament (ACL) reconstruction (ACLR) has higher failure rates in young active patients returning to sports as compared with older, less active individuals. Augmentation of ACLR with an anterolateral procedure has been shown to reduce failure rates; however, indications for this procedure have yet to be clearly defined.

Purpose/hypothesis: The purpose of this study was to identify predictors of ACL graft failure in high-risk patients and determine key indications for when hamstring ACLR should be augmented by a lateral extra-articular tenodesis (LET).

Association of Ligamentous Laxity, Male Sex, Chronicity, Meniscal Injury, and Posterior Tibial Slope With a High-Grade Preoperative Pivot Shift: A Post Hoc Analysis of the STABILITY Study.

Background: A spectrum of anterolateral rotatory laxity exists in anterior cruciate ligament (ACL)-injured knees. Understanding of the factors contributing to a high-grade pivot shift continues to be refined.

Purpose: To investigate factors associated with a high-grade preoperative pivot shift and to evaluate the relationship between this condition and baseline patient-reported outcome measures (PROMs).

Lateral Extra-articular Tenodesis Reduces Failure of Hamstring Tendon Autograft Anterior Cruciate Ligament Reconstruction: 2-Year Outcomes From the STABILITY Study Randomized Clinical Trial.

Background: Persistent anterolateral rotatory laxity after anterior cruciate ligament (ACL) reconstruction (ACLR) has been correlated with poor clinical outcomes and graft failure.

Hypothesis: We hypothesized that a single-bundle, hamstring ACLR in combination with a lateral extra-articular tenodesis (LET) would reduce the risk of ACLR failure in young, active individuals.

Study Design: Randomized controlled trial; Level of evidence, 1.

Blockade of nitric oxide formation in the rat brain does not disturb development of endotoxin tolerance.

The involvement of nitric oxide (NO) in tolerance development to endotoxin has been proposed because peripherally administered NG-nitro-L-arginine methyl ester (L-NAME) (NO synthases inhibitor) delays the endotoxin tolerance formation. Since L-NAME is capable of crossing the blood-brain barrier, the question arises of where activity of NO synthases (inside or outside the blood-brain barrier) is crucial for development of endotoxin tolerance. To clarify the role of different NO synthases (NOS) isoforms, acting in the brain, on the tolerance development, effects of highly selective iNOS and nNOS inhibitors on stepwise attenuation of febrile response during tolerance formation were examined in freely moving biotelemetered rats.

The changes of sialic acid concentration and content in apolipoprotein B-containing lipoproteins in the sera of alcoholics.

Aims: The aim of this study was to investigate the changes associated with alcohol abuse in the structure and metabolism of lipoproteins, in particular, the content of sialic acid (SA).

Methods: The level of SA in apolipoprotein B (apoB)-containing lipoproteins was determined by using enzymatic assay followed by the precipitation step in 126 alcohol-dependent men.

Results: Increased level and content of SA in apoB-containing lipoproteins was found not only in the hyperlipidemic alcoholic subjects but also in normolipidemic subjects.

[Effect of body iron stores in the indicators of alcohol abuse and alcoholic liver injury].

Unlabelled: Chronic alcohol abuse disrupts iron homeostasis in the body leading to its deposition in the liver. Accumulation of iron in the liver can lead to organ damage and the development of alcoholic liver disease.

The Aim Of This Study: To assess the impact of body iron stores, as defined by ferritin and transferrin saturation in alcoholics on the value of the indicators of alcohol abuse (carbohydrate-deficient transferrin and the mean corpuscular volume of red blood cells) and the indices of alcoholic liver damage (gamma-glutamyltransferase, aspartate and alanine aminotransferase).

[Vitamin B12 concentration in the blood of alcoholics].

Unlabelled: Vitamin B12 is an enzymatic cofactor for metabolism of homocysteine to methionine. The metabolism of homocysteine is affected by alcohol abuse. THE AIM of the study was to evaluate an effect of alcohol abuse and alcoholic liver disease on the serum level of vitamin B12.

Relationship between plasma folate and homocysteine concentrations in alcoholics according to liver enzyme activity.

The aim of this study was to evaluate the relationship between folate and homocysteine levels in alcoholics taking into consideration the liver enzyme activity as sensitive markers of hepatocellular injury. Folate and homocysteine concentrations did not differ between alcoholics classified according to the liver enzyme activity. The association between folate and homocysteine levels exists in the alcoholics with normal liver enzyme activity and in the controls.

The assessment of serum soluble transferrin receptor in alcoholics.

The consumption of large amounts of alcohol disturbs body iron metabolism and leads to increase of body iron stores and may cause various hematologic changes. Both, iron overload and iron depletion could have effect on the metabolic, transit and storage pools. These pools and its indicators were evaluated previously in abusers, but there is no information concerning the serum soluble transferrin receptor (sTfR) as a new marker of transit compartment.

Application of ozonotherapy in chronic inflammation of the urinary bladder.

Introduction. Chronic inflammation of the urinary bladder (CIB) is a disease entity which mostly concerns young women and which is connected with their short urether and vicinity of vagina sexual activity. Frequent recidication, in spite of use of new generation of antibiotics - often of considerable cost - have a significant influence upon life of the patients.
