MCPA decomposition method in soil matrix using ozone as an oxidant ***

In presented research a method for remediation of MCPA contaminated soil based on the combination of fluidization process technique and ozone was utilized. Exposition of soil contaminated with MCPA at the concentration of 0,1 % w/w on the a mixture of air and ozone allowed for removal of over 90% of MCPA in form of MCPA 2-ethylhexanol-ester (MCPA 2-EHE) in laboratory conditions. The efficacy of the method was proven by GC-MS analysis of MCPA concentration profile during soil remediation procedure and by comparing of kinetic data, such as half life time, with the natural half life time of MCPA in the soil.

SGLT2-Inhibitors - significant role in Heart Failure treatment

Heart failure (HF), which has a high morbidity and mortality rate, is nevertheless a common and crippling ailment, especially in older populations. The complicated pathophysiology of heart failure (HF), which includes oxidative stress, endothelial dysfunction, fibrosis, and inflammation, is frequently not sufficiently treated despite advances in medication. Inhibitors of the sodium-glucose co-transporter 2 (SGLT2) have become a key treatment for HF in patients with varying left ventricular ejection fractions (LVEF). SGLT2 inhibitors have been shown in recent clinical trials to considerably lower hospitalization rates for heart failure, cardiovascular mortality, and all-cause mortality. The mechanisms of SGLT2 inhibitors, such as better ventricular loading, increased heart metabolic efficiency, and decreased inflammation and necrosis, are covered in this review. Additionally, we provide an overview of four important clinical trials—DAPA-HF, EMPEROR-Reduced, EMPEROR-Preserved, and DELIVER—highlighting their effectiveness in lowering unfavourable cardiovascular outcomes for patients with heart failure who have preserved (HFpEF), slightly reduced (HFmrEF), or reduced (HFrEF). The results validate the need for SGLT2 inhibitors in all-inclusive HF treatment plans by highlighting their adaptability and safety in a range of clinical contexts

Lactase Deficiency and Lactose Intolerance: Current Understanding and Future Directions

Introduction and purpose: Lactose, the primary carbohydrate in milk, requires the enzyme lactase for digestion. Deficiency in lactase activity leads to lactose intolerance, causing gastrointestinal symptoms. Understanding the genetic and environmental factors influencing lactase expression and activity is crucial. Moreover, accurate diagnostic methods and effective treatments are needed to manage lactose intolerance. This review aims to explore the current knowledge on lactase deficiency, lactose intolerance, diagnostic methods, and treatment options. State of knowledge:  Lactase deficiency encompasses congenital, primary, and secondary forms, each with distinct etiologies. Although often used interchangeably, lactase deficiency and lactose intolerance differ. However, the association between lactase deficiency and lactose intolerance is complex, influenced by various factors including dietary habits, gut microbiota, and gastrointestinal motility. Diagnostic methods are limited, and treatment strategies primarily involve dietary modifications, lactase supplementation, and probiotics.  Conclusion: Lactose intolerance presents significant clinical challenges, often underrecognized and misdiagnosed. Despite diagnostic advancements further research is needed to refine diagnostic accuracy. Treatment focuses on dietary adjustments, enzyme supplementation, and probiotics. Balancing symptom relief with nutritional adequacy is essential. Future studies should explore the role of gut microbiome modulation in lactose intolerance management through clinical trials.&nbsp

In response to this, we aim to demonstrate the diversity of alternative pain management techniques in this review and identify conditions where such techniques may be beneficial to patients. State of knowledge: This paper evaluates some of the most common alternative pain management methods (acupuncture, massage, chiropractic, mind body therapies, herbal medicine, music therapy)  and their application in specific cases of chronic pain.  We also describe the possible mechanisms of action involved in the effectiveness of these techniques, based on contemporary studies. Summary: In conclusion, there are conditions where alternative medicine may be beneficial for patients suffering from chronic pain. The studies taken into account showed the best effects for chronic musculoskeletal pain treated with methods such as acupuncture and massage. Mind-body therapies may reduce stress levels and symptoms of depression associated with chronic pain, consequently improving the quality of patients' lives. However, alternative methods should not yet be considered as replacements for conventional drug therapy. More studies are needed to evaluate whether alternative therapies will play a significant role in chronic pain management in the future

Supplementation of vitamin D in children with obesity and vitamin D deficiency - review of outcomes in terms of obesity parameters and comorbidities

In recent years, vitamin D deficiency and obesity in paediatric population have reached epidemic levels worldwide as crucial health concerns with far-reaching consequences. There has been a substantial growth in studies dedicated to these two public health issues over the last years. Numerous studies have confirmed that excess body weight has negative impact on vitamin D metabolism, leading to a higher risk of low levels of this essential vitamin, among individuals who are overweight or obese. Vitamin D deficiency may play a role in the development of obesity-related conditions as insulin resistance, type two diabetes, NAFLD and cardiovascular disease due to anti-inflammatory properties, impact on the endocrine system and metabolic functions of this vital nutrient. Vitamin D supplementation seems to be a beneficial addition to pharmacology and lifestyle changes during obesity treatment

Acne vulgaris and treatment with topical retinoids - adapalene and tretinoin

Introduction and purpose: Acne vulgaris is a disease that mainly affects young people and is associated with overactive sebaceous glands. The disease mainly affects the face but can also occur on the back. Depending on the clinical picture, we can distinguish different types of acne and make our treatment dependent on it. The aim of the study will be to compare the effects of topical retinoids on acne vulgaris. State of knowledge: Topical retinoids have a direct anti-inflammatory effect and prevent the formation of blackheads and microcomedones. Five retinoids are currently available for topical treatment of acne vulgaris. We distinguish three generations. The mechanism of action is not fully understood, but it is known that they react with the RAR and RXR receptors. In the review paper, we will compare the effects of adapalene with tretinoin. Conclusion: According to the indicated study results, there is no significant difference in the effect of treatment with adapalene or tretinoin. Adapalene showed less irritation during treatment than tretinoin. The most important thing during acne treatment is choosing the right concentration and formulation by the dermatologist so that the patient does not stop treatment

The effect of preanalytical phase on the stability of the osmotic fragility and morphological changes in erythrocytes in cattle (Bos taurus)

Hereditary spherocytosis in cattle is a disorder resulting from a nonsense mutation in the SLC4A1 gene, which encodes band 3 membrane protein. This membranopathy leads to the production of spherically-shaped RBCs with reduced deformability and a shorter lifespan in circulation. Laboratory diagnosis of hereditary spherocytosis commonly relies on the erythrocyte osmotic fragility test (OFT), which is time- and labour-consuming and can be influenced by preanalytical factors. The aim of the study was to determine the effect of the preanalytical phase on the stability of osmotic fragility and morphological changes in bovine erythrocytes. Blood was collected from the tail vein of Holstein-Friesian cows (n = 20) into tubes with EDTA or lithium heparin. Erythrocyte resistance to haemolysis was measured by the osmotic fragility test immediately after blood collection and 24, 48 and 72 hours after storage at 4C or at room temperature. Thin blood smears were also prepared, stained and examined for cell morphology. The results showed that bovine erythrocyte osmotic fragility remains stable during 24-hour storage at 4C irrespective of the anticoagulant used. This suggests that OFT can be performed the day after blood collection if blood is stored at 4C. Bovine erythrocytes stored at room temperature were also found to have reduced osmotic resistance. However, heparin better preserves the osmotic resistance of bovine erythrocytes at room temperature. Erythrocytes undergo changes during storage. The microscopic examination of cell morphology revealed rapid transformation of bovine discocytes into various stages of echinocytes during the first three days of storage
