SIMONA CAVALU_ Bone Cement silver joam2007Simona Cavalu
This study evaluated two types of silver-doped bone cement composites for their properties and ability to release silver ions with antibacterial effects. Electrochemical measurements showed both composites reduced calcium ion concentration in simulated body fluid over 14 days, with one composite releasing more silver ions within 5 hours. Scanning electron microscopy images revealed both composites developed hydroxyapatite crystal structures on their surfaces after 14 days, indicating bioactivity. Infrared spectroscopy confirmed mineral deposition and showed one composite absorbed more water over time. The antibiotic-containing composite showed greater mineralization and formation of a calcium phosphate layer, suggesting it may be more suitable for applications requiring bone growth.
This document summarizes a study that compares the microstructure, bioactivity, and biocompatibility of two types of acrylic bone cements: BIOLOS3® and ANTIBIOTIC SIMPLEX®. Electrochemical measurements, SEM imaging, and FTIR spectroscopy were used to analyze the materials after incubation in simulated body fluid for up to 34 days. The results showed that ANTIBIOTIC SIMPLEX® developed a more intense mineralization layer on its surface, as evidenced by greater calcium phosphate formation and water uptake. Hemolysis testing also indicated ANTIBIOTIC SIMPLEX® had better blood compatibility. In conclusion, the antibiotic-containing cement demonstrated superior in vitro bioactivity and bi

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

Storyboard on Skin- Innovative Learning (M-pharm) 2nd sem. (Cosmetics)MuskanShingari
Skin is the largest organ of the human body, serving crucial functions that include protection, sensation, regulation, and synthesis. Structurally, it consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous layer).
1. **Epidermis**: The outermost layer primarily composed of epithelial cells called keratinocytes. It provides a protective barrier against environmental factors, pathogens, and UV radiation.
2. **Dermis**: Located beneath the epidermis, the dermis contains connective tissue, blood vessels, hair follicles, and sweat glands. It plays a vital role in supporting and nourishing the epidermis, regulating body temperature, and housing sensory receptors for touch, pressure, temperature, and pain.
3. **Hypodermis**: Also known as the subcutaneous layer, it consists of fat and connective tissue that anchors the skin to underlying structures like muscles and bones. It provides insulation, cushioning, and energy storage.
Skin performs essential functions such as regulating body temperature through sweat production and blood flow control, synthesizing vitamin D when exposed to sunlight, and serving as a sensory interface with the external environment.
Maintaining skin health is crucial for overall well-being, involving proper hygiene, hydration, protection from sun exposure, and avoiding harmful substances. Skin conditions and diseases range from minor irritations to chronic disorders, emphasizing the importance of regular care and medical attention when needed.
The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.
