Revathy V Nair, Shefrin S, Akhil Suresh, Anoop K R, Sreeja C Nair
In the present investigation, the effect of timolol maleate loaded ocuserts was studied as an alternative for conventional anti-glaucoma formulation. Ocuserts were prepared using natural polymer sodium alginate and ethyl cellulose. Physico-chemical properties along with drug entrapment efficiency (94-98%), content uniformity (93.1% ± 0.264-98.00% ± 0.321), in vitro drug release (83.42% ± 0.35 at end of 12 hours), ex vivo permeation all showed satisfactory results, which was found to follow zero order kinetics...

BACKGROUND/OBJECTIVES: Behavioral problems in individuals with Alzheimer's disease (AD) impose major management challenges. Current prevention strategies are anchored to cognitive outcomes, but behavioral outcomes may provide another, clinically relevant opportunity for preemptive therapy. We sought to determine whether personality changes that predispose to behavioral disorders arise during the transition from preclinical AD to mild cognitive impairment (MCI). DESIGN: Longitudinal observational cohort study...

Dnyanesh Takalkar, Namita Desai
This paper focuses on the development and evaluation of mucoadhesive vaginal gel of fluconazole using nanolipid carriers to enhance tissue deposition in treating vulvovaginal candidiasis. Treatment of vulvovaginal candidiasis includes antimycotic agents prescribed for 1 to 7 days or longer, in relapse either orally or topically. The delivery of fluconazole as nanolipid carriers in vaginal gel can be proposed as suitable alternative to the existing conventional formulations to improve the patient acceptability, compliance and localized drug action...

According to ISO 10993 standards for biocompatibility of medical devices, skin irritation is one of the three toxicological endpoints to be always addressed in a biological risk assessment. This work presents a new protocol to assess this endpoint in vitro rather than in vivo. The protocol was adapted to medical devices extracts from the OECD TG 439 with the SkinEthic™ RHE model as test system. It was challenged with irritant chemicals, Sodium Dodecyl Sulfate, Lactic Acid and Heptanoic Acid spiked in polar solvents, sodium chloride solution or phosphate buffer saline and non-polar solvent, Sesame Oil...

BACKGROUND: There has been no study on radiologic changes after medial ulnar collateral ligament (MUCL) reconstruction and related clinical features. METHODS: Data from 39 baseball players who underwent MUCL reconstruction were collected and analyzed. The baseball players were classified into 2 groups according to the starting point of the humeral tunnel: (1) the lower tip of the medial epicondyle (group NA, n = 21) and (2) the remnant of the MUCL (group A, n = 18)...

Many studies have associated sleep alterations with the severity of irritable bowel syndrome (IBS) symptoms, but the direct pathophysiological relationship has not been clarified. In addition, alterations in noradrenergic signaling have been implicated in the pathophysiology of IBS, and alpha2-adrenoceptors are potential treatment targets. We have previously shown that acceleration of gastrointestinal transit (GIT) elicited by intermittent rapid eye movement (REM) sleep deprivation stress may fulfill the profile of a model of IBS...

Two types of biocompatible surfactants were evaluated for their capability to formulate skin-friendly/non-irritant microemulsions as vehicles for two poorly water-soluble model drugs differing in properties and concentrations: alkyl polyglucosides (decyl glucoside and caprylyl/capryl glucoside) and ethoxylated surfactants (glycereth-7-caprylate/ caprate and polysorbate 80). Phase behavior, structural inversion and microemulsion solubilization potential for sertaconazole nitrate and adapalene were found to be highly dependent on the surfactants structure and HLB value...

This work reports the purification of new potent scorpion neuropeptide, named BotAF, by an activity-guided screening approach. BotAF is a 64-residue long-chain peptide that shares very high similarity with the original β-like scorpion toxin group, in which several peptides have been characterized to be anti-nociceptive in rodents. BotAF administration to rodents does not produce any toxicity or motor impairment, including at high doses. In all models investigated, BotAF turned out to be an efficient peptide in abolishing acute and inflammatory (both somatic and visceral) pain in rodents...

Dietary restriction of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) is effective in the management of functional gastrointestinal symptoms that occur in irritable bowel syndrome (IBS). Numerous reviews have been published regarding the evidence for their restriction in the low FODMAP diet; however, few reviews discuss the implementation of the low FODMAP diet in practice. The aim of this review is to provide practical guidance on patient assessment and the implementation and monitoring of the low FODMAP diet...

BACKGROUND: Impairment of cognitive function as well as negative symptom is the major factor causing the decline of a patient's functioning in chronic stages of schizophrenia. However, until now, there were no definite treatment options that could effectively reduce the impairment. CASE PRESENTATION: We report a case of mood dysregulation associated with use of Ginkgo biloba in a patient with schizophrenia. After Ginkgo biloba was given, the patient experienced cluster symptoms of mood dysregulation including irritability, difficulty in controlling anger, agitation and restlessness...

With the increasing use of animal-based biomaterials for regenerative medical applications, the need for their safety assessment is paramount. A porcine cholecyst-derived scaffold (CDS), intended as a muscle repair graft, prepared by a nondetergent/enzymatic method was engrafted in a rat abdominal wall defect model. Host tissue-scaffold interface samples were collected 2, 8, and 16 weeks postimplantation and evaluated by histopathology, immunohistochemistry, and electron microscopy. The nature of the tissue reaction was compared with those induced by a jejunum-derived scaffold (JDS) prepared by the same method and a commercial-grade small intestinal submucosa (CSIS) scaffold...

The first step in the development of skin sensitisation to a chemical, and in the elicitation of further allergic contact dermatitis (ACD), is the binding of the allergen to skin proteins after penetrating into the epidermis. The so-formed antigenic adduct is then recognised by the immune system as foreign to the body. Sensitising organic hydroperoxides derived from autoxidation of natural terpenes are believed to form antigens through radical-mediated mechanisms, although this has not yet been established...

PURPOSE: The optimal management of infantile nystagmus syndrome (INS) is still unclear. Contact lenses (CL) may be superior to glasses in improving visual function in INS but it is not known whether their beneficial effects are due to optical correction alone, or to an additional proprioceptive effect, and whether soft CLs would be as effective as rigid CLs. There is little data on feasibility and and the present study aimed to provide this information. METHODS: We completed a pilot Randomized Control Trial (RCT) at a single tertiary referral centre in London, UK...

Irritable Bowel syndrome (IBS), the most common chronic functional gastrointestinal disorder, is categorized as IBS-C and IBS-D, which are equivalent to Ghoolenj Rihi and Maghs Rihi in Iranian traditional medicine. One of the main applications of Zataria multiflora Boiss in traditional medicine is its efficacy in the gastrointestinal tract with symptoms such as IBS. The aim of this study was to evaluate the efficacy of Zataria multiflora essential oil in management of IBS. We used all the accessible references (electronic and published books, theses, and reports) to write this article...

INTRODUCTION: Individuals with IBS report higher levels of psychological distress compared to healthy controls. Distress has been associated with emotional processing difficulties but studies have not explored how the relationship between distress and emotional processing affects IBS. There is little research on the role of positive affect (PA) in IBS. AIMS: (a) If difficulties in self-reported emotional processing are associated with affect and IBS measures (i...

BACKGROUND: Researchers have described a 'culture of intoxication' among young people. Yet drunkenness remains a socially risky practice with potential to evoke emotions of irritation and even disgust. We consider intoxicated practices that young adults in Melbourne, Australia, described as distasteful, to identify contemporary cultural forces that constrain intoxication and limit how it is enacted. METHOD: Interviews were conducted with 60 participants in Melbourne, Australia, each with recent drinking experience...

Laryngeal and tracheal morbidity is a common complication of endotracheal tube (ETT)-based airway management, and manifests as local irritation, inflammation, and edema. Systemic corticosteroids are commonly administered to manage these conditions; however, their efficacy is inadequate and limited by potential severe side effects. In the present study, a steroid delivery system for local therapy was developed to generate relatively high local drug concentrations and to improve drug efficacy. ETTs were coated with electrospun poly (lactic-co-glycolic acid) (PLGA) nanofibers loaded with mometasone furoate (MF), creating a microscale thick layer...

Mitotane (o,p'DDD) is established in the adjuvant and advanced stage treatment of adrenocortical carcinoma and counteracts both tumour growth and tumour-related steroid production. Both the adrenal glands and the gonads are steroidogenically active organs and share a common embryogenic origin. Here we describe the effects of mitotane in two patients with metastatic Leydig cell tumour (LCT) of the testes and associated severe androgen excess (serum testosterone 93 and 88 nmol/l, respectively; male reference range 7-27 nmol/L)...
