<b>Introduction:</b> Vestibular schwannoma (VS) is the most common cerebellopontinetumor, causing sensorineural hearing loss, tinnitus, and vertigo. Chronic otitis mediawith cholesteatoma presents with recurrent ear discharge and hearing loss, typicallyrequiring surgical intervention. Although the coexistence of VS and cholesteatoma israre, it creates complex diagnostic and therapeutic challenges that necessitate individualized management approaches.

Aminoglycoside antibiotics and loop diuretics are still the main causes of hearing loss in patients, and no specific prevention is available for this drug-induced ototoxicity. The aim of this study was to compare the protective effects of methionine (MET) and glutathione (GLUT) in terms of the reduction in ototoxicity induced by mixtures of amikacin (AMI, an aminoglycoside antibiotic) and furosemide (FUR, a loop diuretic) in a mouse model in which the hearing threshold decreased by 20% and 50%, respectively. : To compare the otoprotective effects of MET and GLUT on AMI- and FUR-induced ototoxicity in mice, an isobolographic transformation of interactions was applied.

Endometrial cancer (EC) is a heterogeneous gynecological malignancy characterized by varied clinical outcomes and complex molecular mechanisms. The dysregulation of cyclin K (CCNK), a key regulator of transcription and cell cycle progression, has been implicated in cancer development. This study aimed to investigate CCNK expression at the protein level in EC tissues and at the mRNA level using in silico analysis.

Endometrial cancer (EC) is the sixth most common cancer in women worldwide, with rising incidence, particularly in economically developed countries where obesity and type 2 diabetes are prevalent risk factors. EC comprises various histological subtypes with distinct behaviors: Type I tumors are generally estrogen-driven with favorable prognosis, while Type II tumors are hormone-independent, aggressive, and associated with poorer outcomes. Dysregulation of the cell cycle, particularly through cyclin-dependent kinases (CDKs) and their regulators like Cyclin D1 (CCND1), plays a crucial role in EC progression and recurrence.

Background: Curcuminoids, the bioactive compounds found in turmeric, exhibit potent antioxidant, anti-inflammatory, and neuroprotective properties. This study aims to enhance the extraction of curcuminoids from turmeric using environmentally friendly solvents supercritical CO (scCO) combined with natural deep eutectic solvents (NADESs) in one process, and to evaluate the resulting biological activity.

Methods: A Box-Behnken statistical design was applied to optimize scCO extraction conditions-pressure, CO volume, and temperature-to maximize curcuminoid yield.

Article Synopsis
  • The study focused on creating films from ethanolic extracts of unshelled Cannabis sativa seeds to support a circular economy and reduce waste.
  • The films combined apple pectin and citrus pectin in an 80:20 ratio and were tested with different concentrations of the extract (0.5, 1.0, and 2.5 wt%).
  • Results showed varying water vapor barrier properties and transparency based on extract concentration, with all films displaying significant antimicrobial activity against bacteria like Salmonella typhimurium and L. monocytogenes.

In the packaging materials sector, increasing globalization has created the need for increased efforts to develop consumer protection measures. Consequently, new packaging materials are being sought to replace petroleum-based materials in the future. For this reason, global awareness of the environmental problems associated with the use of synthetic and non-degradable packaging has increased the attention paid to bio-packaging based on natural and biodegradable polymers.

Entrapping bioactive ingredients like elderberry extract in hydrogels improves their stability and functionality in food matrices. This study assessed the effect of sequential thermal treatment with ultrasound (US) or high hydrostatic pressure (HHP) and treatment duration on pea protein-psyllium hydrogels as elderberry extract carriers. Measurements included color parameters, extract entrapment efficiency, physical stability, textural properties, microrheology, FT-IR, thermal degradation (TGA), SEM images, total polyphenols content, antioxidant activity, and reducing power.

Unlabelled: The aim of this study was to preliminarily determine the content of bioactive components in the fruiting bodies of four previously unstudied mushroom species: , , , , their antioxidant activity and the content of polyphenols, minerals and heavy metals.

Methods: Determination of active compounds by gas chromatography-mass spectrometry was carried out in addition to thermogravimetric determinations, quantitative determination of total polyphenols by spectrophotometry using Folin-Ciocalteu reagent, determination of antioxidant activity using 2,2-diphenyl-1-picryl hydrazyl radical (DPPH) and 2,2'-azino-di-[3-ethylbentiazoline sulphonated] (ATBS). In addition, spectrometric analysis of selected minerals and heavy metals was performed by inductively coupled plasma optical emission spectroscopy (ICP-OES).

Article Synopsis
  • Paragangliomas are neuroendocrine tumors located in various body regions, and their surgical removal can be complicated by nearby critical structures; pre-operative embolisation is used to minimize risks.
  • A study reviewed data from 27 patients with head and neck paragangliomas who underwent selective embolisation, achieving over 75% blood supply occlusion in 81.5% of cases.
  • The procedure was found to be safe, with minimal complications and no neurological deficits, supporting its effectiveness before surgery.

Endometriosis is a gynecological condition where endometrium-like tissue grows outside the uterus, posing challenges in understanding and treatment. This article delves into the deep cellular and molecular processes underlying endometriosis, with a focus on the crucial roles played by cyclins and cytoskeletal proteins in its pathogenesis, particularly in the context of Epithelial-Mesenchymal Transition (EMT). The investigation begins by examining the activities of cyclins, elucidating their diverse biological roles such as cell cycle control, proliferation, evasion of apoptosis, and angiogenesis among ectopic endometrial cells.

Alpha-fetoprotein (AFP) is a protein commonly found during fetal development, but its role extends beyond birth. Throughout the first year of life, AFP levels can remain high, which can potentially mask various conditions from the neurological, metabolic, hematological, endocrine, and early childhood cancer groups. Although AFP reference values and clinical utility have been established in adults, evaluating AFP levels in children during the diagnostic process, treatment, and post-treatment surveillance is still associated with numerous diagnostic pitfalls.

Drug-induced ototoxicity resulting from therapy with aminoglycoside antibiotics and loop diuretics is one of the main well-known causes of hearing loss in patients. Unfortunately, no specific protection and prevention from hearing loss are recommended for these patients. This study aimed at evaluating the ototoxic effects produced by mixtures of amikacin (AMI, an aminoglycoside antibiotic) and furosemide (FUR, a loop diuretic) in the mouse model as the hearing threshold decreased by 20% and 50% using auditory brainstem responses (ABRs).

This article presents contemporary opinion on the role of alpha-fetoprotein in oncologic diagnostics and treatment. This role stretches far beyond the already known one-that of the biomarker of hepatocellular carcinoma. The turn of the 20th and 21st centuries saw a significant increase in knowledge about the fundamental role of AFP in the neoplastic processes, and in the induction of features of malignance and drug resistance of hepatocellular carcinoma.

Alpha-fetoprotein (AFP) is one of the biochemical components of the triple (T-3) and quadruple (T-4) test used so far in prenatal screening mainly for trisomy 21 (T21) and neural tube defects (NTDs). Based on many years of experience and data collected during these studies, a variety of factors have been identified that can affect a pregnant woman's serum AFP level, and thus the risk assessment of trisomy 21 (T21) and neural tube defects. These include both unaccounted for purely medical data (e.
