When smell becomes the shadow: a case report of olfactory reference disorder

Olfactory Reference Disorder (ORD) is defined by a continuous fixation on the belief that one is exuding an unpleasant or offensive body odor or breath, which is either imperceptible or only marginally detectable by others. This report describes a 26-year-old male who sought assistance due to his conviction of emitting a foul odor from his mouth and nose, prompting him to visit multiple dentists and otolaryngologists. His condition led to social withdrawal, resulting in feelings of despair and powerlessness. The Mental Status Examination (MSE) revealed a depressed mood, suicidal thoughts, and an obsession with the perceived smell. Both MRI and EEG findings were normal. The patient was diagnosed with ORD and depression based on the Yale-Brown Obsessive-Compulsive Scale – Olfactory Reference Syndrome (YBOCS-ORS) and the Hamilton Depression Rating Scale (HAM-D). He was prescribed fluoxetine at a dosage of 40 mg, along with a low dose of olanzapine. Furthermore, Cognitive Behavioral Therapy (CBT) was initiated to support his recovery. Ultimately, the patient secured employment. Although he continued to have lingering thoughts of an unpleasant odor at a low intensity, he managed to function adequately and engage in social interactions more effectively.

A study on mechanical properties and durability of vermiculite concrete

Concrete is a material which is used in construction. Weight of concrete plays a major role in the construction industry. If the weight of the concrete is increased, it will pose more structural problems on the later date of construction. It also increases the cost of construction, without any specific benefit. So if lightweight concrete is used, it not only reduces cost of construction, but also not poses any structural problems unnecessarily. Light weight concrete also aids workers in smooth handling of materials. In this study, vermiculite in the form of exfoliated form is used to replace partially natural sand. By this action dead weight of the structure is reduced. Once the dead weight of structure is reduced, it in turn reduces cost of construction. In this study three mixes were casted with the cement content of 383 kg/m3 in M20 concrete and the water cement ratio of 0.45 is chosen. Vermiculite at 10%, 20% and 30% are choosing to partially replace the natural sand. The Tests conducted on concrete for evaluating mechanical properties include compressive strength and split tensile strength. For evaluating durability properties, tests like acid resistance, sulphate resistance, chlorine penetration and water absorption.

New dimension in higher education in india

Higher Education has an important role in the task of rebuilding a nation and it pavCes the way for overall development of a nation. The twentieth century has witnessed several revolutions like Green revolution, White revolution, I.T revolution, so on and so forth, taking human civilization to new heights. At the start of 21st century, we gave a lot of importance given to higher education. Every country realized the value of higher education and the benefits that accrue from it. “The social demands for higher education continue to increase. The inabilities of the state to support this growing demand result in new financing arrangements for higher education. The recent reforms in this area could be broadly divided into two categories: the privatization of public institutions and the establishment of private institutions of higher education. Privatization implies the application of market principles in the operation of public institutions, while ownership rests within the public domain. Promotion of the private sector implies the growth and expansion of the non-state sector in higher education, and very often this sector does not rely on state funding for its growth and expansion. Both of these measures have paved the way for market operations in higher education

Coping up with covid-19 in india: a new way of surviving indian hospitality industry

India's hotel and hospitality industry occupancy decreased significantly in the first quarter of 2020, as the outbreak of COVID-19 affects different segments of the market. The outbreak of the novel coronavirus (COVID-19) has inflicted a blow on industries around the world, but maybe none as devastating as hospitality and travel. Depending on the length of the pandemic, companies across the industry adjusted growth forecasts for 2020, estimated profits to be conservatively 40-50 percent lower than expected before the outbreak. The effect on hospitality demand is greater than many other sectors, but even among hotels, air and cruise ships, and restaurants it is varied. Hotels and airlines operate at half capacity, with both business and leisure travelers canceling scheduled trips and not arranging any for the near future.The present article aims to study some novel practices for the survival of hospitality industries once the lockdown is over.

Phytochemical analysis and anti-emetic activity of illicium verum hook. f. fruit by chick emesis model

Emesis is defined as a forceful expulsion of stomach contents via the mouth. The adverse effects of available anti-emetic drugs potentiate us to evaluate natural products to explore effective natural anti-emetics with fewer side effects. The fruits of Illicium verum Hook. f. were selected for anti-emetic activity based on their folkloric use against gastrointestinal complaints. Crude methanolic extract and its aqueous, dichloromethane, ethylacetate and hexane fractions were evaluated using the copper sulphate-induced chick emesis model. Emesis was induced by the oral administration of copper sulfate 10 ml/kg body weight and metoclopramide (150 mg/kg p.o.) as a standard anti-emetic drug. The anti-emetic effect was observed by calculating the mean decrease in the number of retches compared to that of the control. Methanolic extract and its fractions were tested at 25, 50 and 75 mg/kg oral doses. Among all tested fractions, ethyl acetate showed the highest (94.46%), and hexane showed the lowest (56.30%) anti-emetic activity at 50 mg/kg. Further, isolation and purification from the same fractions are in process to discover effective natural anti-emetic compound(s) with less unwanted effects.

Evaluating the effects of insulin, metformin and glibenclamide on the pups’ prefrontal cortex and oxidative stress markers of streptozotocin-induced diabetic pregnant rats

There is an upsurge in gestational diabetes mellitus with many devastating consequences for the mother and developing fetus. Insulin therapy remains a mainstay. However, insulin is expensive and comes with the pain of multiple injections. Therefore, there is a need to explore commonly administered oral hypoglycemic agents to cater for the increasing gestational diabetes mellitus-associated neurological complications. This study assesses the effects of glibenclamide, metformin and insulin on the pups’ prefrontal cortex in diabetic pregnant rats. 35 sexually matured adult female rats weighing between 120 g and 160 g were used and assigned into five groups (A to E) of seven rats each group. Diabetes was induced by streptozotocin (45 mg/kg and 35 mg/kg; ip). Hyperglycemic rats were treated with insulin (1.0 UI daily), metformin (200 mg/kg/day) and glibenclamide (0.6 mg/kg/day). Body weight and blood glucose levels were evaluated. Rats were sacrificed at 18-day gestation, the pups were harvested, and their brains were processed for tissue oxidative stress markers and various histological examinations. Glibenclamide and metformin caused a significant blood glucose reduction at 37.9% and 40.7%, respectively, compared to the insulin group (33.09%). There was no significant difference in the body-organ ratio in rats treated with metformin when compared to rats treated with insulin. Metformin and glibenclamide had a significant increase in tissue glutathione reductase and a decrease in malondialdehyde compared with insulin and diabetic control groups. The pups’ prefrontal cortex showed degenerated neuronal cells in the diabetic control animals. The diabetic rats treated with metformin and glibenclamide showed improved pyramidal neurons compared with diabetic and insulin groups. This study suggests that metformin and glibenclamide glycemic control may prevent and improve antioxidant enzymes and reverse some neurotoxic effects caused by streptozotocin-induced diabetes in rats.

“the person with maximum knowledge will win the race”: conceptualizing knowledge in microbusinesses

The concept of knowledge and the process of knowledge sharing in ethnic minority microbusinesses remain neglected in contemporary debates even if their role for economic development is recognized. Drawing on a culturalist view, we explore how knowledge is defined and shared in a local niche market. Thematic analysis of semistructured qualitative interviews with 32 owner managers and 11 employee-managers reveals that, contrary to studies on larger firms, local knowledge creation and sharing narrowly based on ethnic strengths are valuable sources of competitive advantage. Our study has implications for researchers, policymakers, and practitioners in exploring, supporting, and integrating ethnic minority microbusinesses.

Antitussive effect of aerial parts of caesalpinia pulcherrima by sulphur dioxide induced cough in rats

Natural products have played an essential role in treating human diseases for thousands of years. According to WHO, 80% of the world’s population relies on traditional medicines to cure and prevent ailments. Numerous plants have been reported to have antitussive activity. Our present study aimed to evaluate the antitussive effect of aerial parts of ethanolic extract of Caesalpinia pulcherrima (Caesalpiniaceae) at 200 and 400 mg/kg doses in healthy albino rats. Caesalpinia pulcherrima is an ornamental plant, usually 3.7-4.3 m in height, known as Peacock flower and is used traditionally to treat cough, bronchitis and asthma. Cough significantly affects human health and is the most common reason to visit physicians. Cough may be produced due to disease, allergens, pollutants and respiratory infections. Any mechanical or inflammatory change provokes the afferent or sensory nerves in the larynx and tracheobronchial, resulting in a cough. In this study, cough was induced by using the sulphur dioxide induction method. Animals were divided into four groups of 7 animals each, and all the drugs were administered orally. Group I was a control group, while group II was a standard taking Prospane. The extract showed highly significant results at 200 and 400 mg/kg doses compared to the control. So, it proves and supports the traditional use of Caesalpinia pulcherrima to relieve cough.

An application of modified path matrix approach for detection of isomorphism among epicyclic gear trains

The identification of isomorphism in epicyclic gear trains has been found a lot of attention by researchers for the last few years. Various methods have been suggested by different authors for the detection of isomorphism in planer kinematic chains and epicyclic gear trains (EGTs), but everyone has found some difficulties to address new issues. In this paper, a modified path matrix approach was presented in order to compare all the distinct geared kinematic mechanisms. A new method based on the matrix approach and corresponding train values is required to identify isomorphism among epicyclic gear trains and their mechanisms. The proposed method was examined on the basis of various examples from four-link, five-link, six links, and eight-link one-degree-of-freedom EGTs and six links two-degree-of-freedom EGTs. All the examples have been found satisfactory results with existing literature.

Behavioural effects of vitamin c with haloperidol in mice

Vitamin C causes a significant change in pharmacological effects of some drugs which may lead to unpredictable responses. Vitamin C-haloperidol interaction has not been confirmed in vivo. This study was aimed to investigate the influence of vitamin C on some pharmacological effects of haloperidol (extrapyramidal side effects caused by the antipsychotic haloperidol). Albino male mice (n = 24, body weight of 20 - 40 gm) were divided into four groups and each of consists of six mice. Group I (control): given 1% Tween 80 solution, group II: given vitamin C in a dose of 100 mg/kg, group III: given haloperidol (2 mg/kg), while group IV: given a combination of vitamin C and haloperidol. All the treatments were given by intraperitoneal route of administration. Three sub-acute doses of different treatments were given at 24:0, 5:0, 1:0 hour before scoring. Parameters scored were catalepsy, ptosis, rigidity and akinesia. The experiment was repeated using vitamin C in a dose of 500 mg/kg. Both doses of 100 and 500 mg/kg of vitamin C significantly antagonized the effect of haloperidol by decreasing all the tested parameters. The results indicate that vitamin C decreases extrapyramidal side effects caused by the antipsychotic haloperidol and show that it successfully decreases catalepsy, ptosis, rigidity and akinesia in mice.

Characteristics-centered cryptography with cloud revocation authority and its applications

Identity-based encryption (IBE) is a public key cryptosystem and eliminates the demands of public key infrastructure (PKI) and certificate administration in conventional public key settings. Because of the absence of PKI, the revocation drawback could be a crucial issue in IBE settings. Many rescindable IBE schemes are planned relating to this issue. Quite recently, by embedding associate outsourcing computation technique into IBE, Li et al. planned a rescindable IBE theme with a key-update cloud service supplier (KU-CSP). However, their theme has 2 shortcomings. One is that the computation and communication prices are above previous rescindable IBE schemes. The opposite disadvantage is lack of measurability within the sense that the KU-CSP should keep a secret worth for every user. Within the article, we have a tendency to propose a replacement rescindable IBE theme with a cloud revocation authority (CRA) to resolve the 2 shortcomings, namely, the performance is significantly improved and the CRA holds only a system secret for all the users. For security analysis, we demonstrate that the proposed scheme is semantically secure under the Decisional Bilinear Diffie-Hellman (DBDH) assumption. Finally, we have a tendency to extend the planned rescindable IBE theme to gift a CRA-aided authentication theme with period-limited privileges for managing an outsized range of varied cloud services.
