Background: Worldwide, rural populations are recognized to be exposed to increased health challenges due to their living and working environment, socioeconomic status, and access to health services. According to the Romanian Country Health Profile 2023, approximately 46% of all deaths recorded in Romania in 2019 could be attributed to behavioral risk factors such as tobacco smoking, dietary risks, alcohol consumption and low physical activity. No data on rural versus urban areas are available to date, and research is needed to document health inequalities, identify barriers to health services, and explore solutions.

Climate change is exacerbating forest disturbances through more frequent and more intense droughts and fires, undermining their ability to recover from such disturbances. The response of fast-growing early-successional species to drought is poorly understood, despite their key role in ecological succession and their ability to enhance ecosystem resilience. Here, we compared the growth responses to drought events of three early-successional species (silver birch, black poplar, and Scots pine) with that of one late-successional species (European beech) across their natural distribution ranges in Europe.

X-IGA Used for Orthotropic Material Crack Growth.

Materials (Basel)

August 2024

Romanian Academy of Technical Sciences, B-dul Dacia 26, 030167 Bucharest, Romania.

In this paper, we propose a new approach for numerically simulating the growth of cracks in unidirectional composite materials, termed extended isogeometric analysis, evaluating the maximum stress intensity factor and T-stress. To validate our approach, we used a small anisotropic plate with two edge cracks, beginning with formulating the governing equations based on the energy integral method, Stroh's Formula, and the Elastic Law describing the behaviour of anisotropic materials, while considering boundary conditions and initial states. A MATLAB code was developed to solve these equations numerically and to post-process the tensile stress and the stress intensity factor (SIF) in the first mode.

Vibration-Assisted Welding of 42CrMo4 Steel: Optimizing Parameters for Improved Properties and Weldability.

Materials (Basel)

June 2024

Department of Materials Engineering and Welding, Faculty of Materials Science and Engineering, Transylvania University of Brasov, B-dul Eroilor 29, 500036 Brasov, Romania.

This study advances the vibration-assisted welding (VAW) technique for joining medium-carbon, low-alloy steels, which are typically challenging to weld. Traditional welding methods suggest low linear energy and mandatory pre- and post-heating due to these steels' poor weldability. However, VAW employs a vibrating table to maintain part vibration throughout the automatic MIG/MAG welding process.

RGC-32 mediates proinflammatory and profibrotic pathways in immune-mediated kidney disease.

Clin Immunol

August 2024

Division of Rheumatology and Clinical Immunology, Department of Medicine, University of Maryland School of Medicine, Baltimore, MD, USA. Electronic address:

Article Synopsis
  • Systemic lupus erythematosus is an autoimmune disease causing damage to kidneys and organs, which was studied in the context of nephrotoxic nephritis (NTN) as a model for lupus nephritis.
  • The research focused on response gene to complement-32 (RGC-32), finding that its absence in RGC-32 knockout (KO) NTN mice led to reduced proteinuria, improved kidney function, and less severe kidney damage.
  • RGC-32 KO mice also showed decreased recruitment of certain immune cells and less renal fibrosis, suggesting that RGC-32 could be a promising target for new treatments aimed at combatting conditions like lupus nephritis.

Background: Targeting gut dysbiosis to treat chronic diseases or to alleviate the symptoms is a new direction for medical adjuvant therapies. Recently, postbiotics have received considerable attention as they are non-viable probiotic preparations that confer various health benefits to the host without the safety problems associated with using live microbial cells.

Objective: The aim of the study is to obtain selenium (Se) and zinc (Zn) enriched postbiotic biomass and to analyze its modulation effect because these minerals play an important role in reducing gut dysbiosis linked to cardiovascular (CV) diseases.

Medicina (Kaunas)

March 2024

Department of Prosthodontics, Multidisciplinary Center for Research, Evaluation, Diagnosis and Therapies in Oral Medicine, "Victor Babes" University of Medicine and Pharmacy Timisoara, 2 Eftimie Murgu Sq., 300041 Timisoara, Romania.

This paper aims to assess the role of laser therapy in periodontitis through an innovative approach involving computational prediction and advanced modeling performed through network analysis (Gaussian graphical models-GGMs) and structural equations (SEM). Forty patients, exhibiting periodontal pockets with a minimum depth of 5 mm, were randomly divided into two groups: a control group and a laser group. Four specific indicators were measured for each tooth, namely periodontal pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI), and the mean of six measured values was recorded at five time markers (baseline, 6 months, 1 year, 2 years, and 4 years).

Despite the large number of studies on rodent ectoparasites-most of them vectors of epidemiologically important pathogens-infestation patterns remain poorly understood in various ecological contexts, such as the highly patchy agricultural landscapes. We aimed to relate the infestation of rodents to temporal, habitat, and host variables. We assessed the difference in parasite prevalence and mean abundance depending on host sex, age, and body weight, season, and land use intensity.

The aim of this study is to solve a practical problem encountered in the automotive industry, especially the failure of a cracked lower control arm made of al 6062 T6 material during static and crash physical tests, and to characterize the behavior of cracked parts made of aluminum materials using the fracture mechanics parameters. As a first step, we carried out a numerical study and simulation using Abaqus/CAE 2020 software and the finite element method to determine the stress concentration and load limit capacity for different car weight cases. The von Mises stress variation shows crack initiation and propagation to be in the area of the lower control arm's attachment to the vehicle platform, where stress is concentrated.
