The Evolution of Fetal Surgery

Abstract:

Fetal surgery is the newest surgical specialty with a compelling history. The development of fetal surgery began in primates and lambs and, in its most basic form, was first performed in humans in 1965. Since its introduction, the field has expanded and changed dramatically. Several of these changes have involved the ethical aspect of fetal surgery. This field conflicts with the Hippocratic oath mantra of “first do no harm” as one of the patients, the mother, receives no benefit from these procedures. The ethical dilemma resulted in stringent inclusion and exclusion criteria for fetal operations. Initially, fetal surgery was only indicated for life-threatening conditions of the fetus but is now offered in some disease processes to improve quality of life for the child. As the field has matured, it has grown to encompass numerous different types of fetal interventions. Similar to other areas of surgery, the trend has been to migrate from more invasive to less i...

Novel N-Pyrrolylcarboxylic Acid Derivative as a Potential New Analgesic and Anti-Inflammatory Drug

Abstract:

The objective of our study was to evaluate the analgesic and anti-inflammatory activity, as well as possible organ toxicity of 2-3-3-methyl-pentanoic acid (compound 3d), a newly synthesized pyrrolic derivative, structurally similar to Celecoxib. Antinociception was assessed using animal pain models with thermal and chemical stimuli (paw withdrawal, tail-flick and formalin test). Anti-inflammatory activity was measured using the carrageenan-induced paw edema model. Blood samples were collected from the animals to study possible organ toxicity. All experiments were performed on male Wistar rats. The results in our study show that in experimental conditions 2-3-3-methyl-pentanoic acid has analgesic action against thermal and chemical stimuli. This effect is registered after both single and multiple administration of the compound. In the carrageenan model after single a...

Juvenile Idiopathic Arthritis: A Study of 74 Cases in Northeast Brazil

Abstract:

To identify the clinical epidemiological characteristics of patients with juvenile idiopathic arthritis (JIA) monitored at the Lucidio Portella Children’s Hospital (HILP) in northeastern Brazil and to ascertain the frequency and forms of presentation, the most affected joints, the most common joint involvement for each form, the frequencies of positive rheumatoid factor (RF+) and positive antinuclear antibodies (ANA+) in the various forms of presentation, and the most common complications.

Industrial and Biotechnological Applications of Algae: A Review

Abstract:

Algae are a class of photosynthetic organisms found in both marine and freshwaters habitats. As these organisms have a short doubling time, they are considered among fastest growing creatures. They have different pathways to fix atmospheric carbon dioxide and to efficiently utilize the nutrients to convert it into biomass. In few years, a focus has been shifted towards these organisms due to their food and fuel production capability. In fuel industry algae biofuels have been emerged as a clean, nature friendly, cost effective solution to other fuels. Algae fuels are categorized into bio-ethanol, biogas, bio-hydrogen, biodiesel and bio-oil. Algae as a food have been explored for different applications as in production of single cell proteins, pigments, bioactive substances, pharmaceuticals and cosmetics. The present review has been prepared to throw a light on enormous applications of algae as food and fuel and also to provide some information about different comme...

Neurovascular Reactivity after Repeated Attacks in Patients with Multiple Sclerosis

Abstract:

Increased neurovascular (NV) reactivity has been shown in patients with relapsing-remitting multiple sclerosis (RRMS) during the acute exacerbation period. However, the NV reactivity after several attacks is not known. We, therefore, have investigated the patients by transcranial Doppler (TCD) using simple visual stimulation after the repeated attack periods.

Early Versus Late Immunomodulatory Therapy in Vogt-Koyanagi-Harada disease

Abstract:

To evaluate early versus late immunomodulatory therapy (IMT) for patients following initial diagnosis of Vogt-Koyanagi-Harada (VKH) disease.

Relationship between Trauma-Related Psychotic Reactions and Post-Traumatic Stress Symptoms: The Mediating Role of Alcohol Use

Abstract:

This study examined the mediating role of alcohol use in the relationship between PTSD symptoms and trauma-related psychotic reactions. A total of 231 participants including 181 females were recruited via web advertisement and flyers. Alcohol use condition, trauma-related psychotic experience, and PTSD symptoms were measured by Feeling the need to Cut down, Annoyed by criticism, Guilty about drinking, and need for an Eye-opener in the morning (CAGE), Psychosis Screening Questionnaire (PSU) and Short screening scale for posttraumatic stress disorder (SSSP). All the participants were asked to finish the questionnaire package on the Internet and were interviewed later to validate the screening. Logistic regression was used to estimate the mediating effect of alcohol use. Results showed that alcohol use played a mediating role between PTSD symptoms and auditory hallucination while this effect didn’t exist between PTSD symptoms and paranoia. Findings indicated that h...

Rapid Calcification of Myocardium as Sequela from Severe Sepsis

Abstract:

A rare case of rapid myocardial calcification following severe sepsis is presented. The report outlines the temporal course, imaging findings, and plausible pathophysiologic mechanisms, including septic cardiomyopathy and calcium‑phosphate imbalance. Implications for critical care follow‑up and cardiology evaluation are discussed.

Morphological and Functional Abnormalities of the Thyroid Gland among End Stage Kidney Disease Patients

Abstract:

Several interactions exist between thyroid and kidney function in many disorders. Many publications explored the relationship between thyroid diseases (TD) and chronic kidney diseases (CKD). However, the morphological thyroid changes in patients with CKD or End Stage Kidney disease (ESKD) were not fully explored. The aim of this study is to explore the morphological and the functional abnormalities of the thyroid gland among ESKD patients as detected by Doppler ultrasound.

Monitoring the Changes in Certain Hematological and Biochemical Parameters in Camels (Camelus Dromedaries) during Postpartum Period

Abstract:

The postpartum period in camel are considered the most critical period for camel's health and for future fertility. The objective of the present study was to compare the clinical examination results and the concentration of hemoglobin, total protein, calcium and progesterone at different instances (1^st, 3^rd and 9^th days) postpartum. Fifteen female camels during the postpartum period (1^st, 3^rd and 9^th days) were included in the present study. Hematological, biochemical profiles and ultrasonographic examination were performed. The clinical examination results were normal and no evidence of clinical disease. The results of the hematological and biochemical findings were within the reference range obtained previously by our research team. The concentrations of hemoglobin, total protein, calcium and progesterone were measured at the 1^st, 3^rd and 9^th days postpartum. Hem...
