Chronic wound management; surgical therapy and complementary nursing with Manuka honey
Objectives. This study aims to analyze the evolution of chronic wounds treated both surgically and by complementary nursing using Manuka honey. The parameters monitored were: presence/persistence of bacterial infection, the duration of healing, the recovery period and the patients\u27 quality of life. Materials and Methods. The study group and the control group each consisted of 10 patients, aged between 50-60 years, with chronic wounds of various etiologies but without other significant systemic pathologies. Data collection was carried out through anamnesis, physical examination and analysis of medical documents. Results. In the study group, the depth of the wound was reduced rapidly and significantly, with complete epithelialization after about four weeks. In the control group, the wound was completely healed by classical treatment, but in eleven weeks and in the form of an unaesthetic keloid scar. The recovery period of a chronic wound appears to be significantly influenced by the use of Manuka honey. Conclusions. Future studies on large groups of patients need to verify the potential therapeutic properties of this compound (anti-inflammatory, antibacterial, antifungal, antioxidant, autolytic debridement, etc.), as well as its adjunctive contribution to wound dressing (maintaining a moist environment and reducing trauma and unpleasant odors)
Interaction of d-Tubocurarine with Potassium Channels: Molecular Modeling and Ligand Binding
ABSTRACT Potassium channels play fundamental roles in physiology. Chemically diverse drugs bind in the pore region of K Ï© channels. Here, we homology-modeled voltage-and Ca 2Ï© -gated
Romanian Organic and Conventional Red Grapes Vineyards as Potential Sources of High Value-Added Products, in a Circular Economy Approach
The use of natural ingredients with active functions has been intensively studied in the last years, as a consequence to consumer preferences for organic products. Application of circular economy principles determined a significant research activity in the viticulture field. The use or re-use of vines parts for so-called nutraceuticals or other consumer-goods applications, are basically centered on their phytochemical and microbiological characterization. Eurostat updates ranks Romania fifth among the EU member states, with a total area under vines of 183,717 hectares. Characterization of four Vitis vinifera L. varieties, out of which one pure Romanian variety (Feteasca Neagra), cultivated in organic and conventional vineyards, together with pedoclimatic conditions have been provided. Data on phytochemical parameters and antimicrobial activity of extracts obtained from different anatomic parts of grapes were included. Analytical protocols and techniques applied were presented, together with data and results interpretation. Several chemometric algorithms have been used as complementary tools for interpretation of the instrumental analytical data
âA. FATUâ BOTANICAL GARDEN IASSY â THE GREENHOUSE
In Iassy, âA. Fatuâ Botanical gardenâs Greenhouse complex (20 buildings with a total area of 3800 sq.m) hosts a remarcable fund of exotic plants (2700 taxa), native especially in subtropical, tropical and ecuatorial areas, on every continent.This paper presents some of the plant collections grown in this space. It comes out that, by number, diversity and value (scientific/decorative) of the taxa, many collections â azaleas and camelias, carnivorous plant, palm trees, bromelias, orchids, cicads, crotons, ficuses â have a unicum value in the country

Barriers and Facilitators for the Romanian Older Adults in Enjoying Physical Activity Health-Related Benefits
Older adults are considered a vulnerable category within the population, which is exposed to an accelerated risk of functional degeneration. The purpose of this study was to explore different facilitating factors and possible existing barriers to being physically active in older age in urban areas of Romania. A cross-sectional survey was conducted among 172 participants who were asked to assess their health, on a scale from 1 to 3, and to fill out two questionnaires: 1. Physical Activity Scale for the Elderly; 2. Depression, Anxiety, and Stress Scale. Participants were also asked to specify to what extent they performed different leisure activities during the last week. SPSS was used for data analysis. The chi-squared test, t-test, ANOVA, and MANOVA emphasised the differences between participants, at p < 0.05. Regarding health condition, 27.3% of participants responded that their health was good, 53.5%âsatisfactory, and 19.2%ânot so good. The results showed significant differences between older adults participating in Elderly Clubs and non-participants, only in terms of PASE leisure. There were significant multivariate effects of the variables Gender and Stable life partner regarding PASE leisure. Weak negative correlations were identified between leisure physical activities and emotional state. Among the proposed leisure activities, watching TV and listening to music represented the most frequent preferences of the participants. The older adults participating in this study preferred to become involved with different physical activities, in conjunction with their habits, health, age, sex, stable life partner, and Elderly Club participation
Regulation of ClC-2 gating by intracellular ATP
ClC-2 is a voltage-dependent chloride channel that activates slowly at voltages negative to the chloride reversal potential. Adenosine triphosphate (ATP) and other nucleotides have been shown to bind to carboxy-terminal cystathionine--synthase (CBS) domains of ClC-2, but the functional consequences of binding are not sufficiently understood. We here studied the effect of nucleotides on channel gating using single-channel and whole-cell patch clamp recordings on transfected mammalian cells. ATP slowed down macroscopic activation and deactivation time courses in a dose-dependent manner. Removal of the complete carboxy-terminus abolishes the effect of ATP, suggesting that CBS domains are necessary for ATP regulation of ClC-2 gating. Single-channel recordings identified long-lasting closed states of ATP-bound channels as basis of this gating deceleration. ClC-2 channel dimers exhibit two largely independent protopores that are opened and closed individually as well as by a common gating process. A seven-state model of common gating with altered voltage dependencies of opening and closing transitions for ATP-bound states correctly describes the effects of ATP on macroscopic and microscopic ClC-2 currents. To test for a potential pathophysiological impact of ClC-2 regulation by ATP, we studied ClC-2 channels carrying naturally occurring sequence variants found in patients with idiopathic generalized epilepsy, G715E, R577Q, and R653T. All naturally occurring sequence variants accelerate common gating in the presence but not in the absence of ATP. We propose that ClC-2 uses ATP as a co-factor to slow down common gating for sufficient electrical stability of neurons under physiological conditions
