Library Services for Students with Disabilities: Barriers and Way Forward.

Libraries form an integral part of any society and provide an impetus for the academic and intellectual growth of the society. They are considered as the repositories of knowledge and should provide information to all without any discrimination on any grounds. Yet, students with disabilities form a vulnerable group who face discrimination and restrictions while accessing the library services. In this paper we have focused on some of the barriers that students with disabilities face while accessing the library services. These have been identified as a) Inaccessible Formats, Materials and Web-Pages b) Inaccessible Libraries c) Lack of Trained Staff in the Libraries. This has been followed by a set of recommendations to make libraries inclusive and accessible for all

The Relationship between Perfectionism Dimensions and Coping Strategies in Postgraduate Clinical Psychology Students and Practitioners

The aim of the study was to explore a relationship between perfectionism dimensions and coping strategies in postgraduate clinical psychology students and practitioners i.e. professionals of an emotionally challenging field. The population consisted of postgraduate clinical psychology students, and those who have recently completed the degree and had conducted some therapeutic sessions individually (N = 100, M = 3% & F = 97%). The measurement tools applied in this study were Frost Multidimensional Scale (FMPS) (FMPS; Frost., Marten., Lahart., & Rosenblate) and Brief Cope Inventory [2]. The research was descriptive correlational study and the statistical analyses was done through SPSS (version 22). The study was conducted during COVID-19 pandemic situation hence, data was collected through online medium. Both the hypotheses got rejected while the data supported newer findings which showed that both the perfectionism dimensions had a weak positive but statistically significant relationship with the dysfunctional coping (except organization). Moreover, results indicate that unemployed participants found to be more organized than those who were employed. The study would be of significant value in developing programs aiming at counseling mental health practitioners with using adaptive coping strategies. As when they enter the professional field they are expected to be perfect in their services, causing them to strive for better and to cope on their own for the sake of providing satisfactory interventions to their patients for their well-being

The Selection of Maxillary Anterior Teeth Width in Kashmiri Population

Introduction: Determining the width of maxillary anterior teeth is a difficult aspect in complete denture fabrication. The width of maxillary anterior teeth is determined by taking various anatomical landmarks on the face as a guide, such as the interpupillary, interalar, intercommissure and interzygomatic distance, etc. The present clinical study was carried out to evaluate the relationships between maxillary anterior teeth measurements (canine to canine and central incisor width) and various horizontal facial parameters. Materials and methods: The facial and dental measurements were obtained directly from 60 Kashmiri  undergraduate dental students by using vernier calliper and dental floss. Result: Correlation analysis was done using Pearson’s correlation analysis and it was determined that the incisor width and canine to canine distance show positive correlation with some of the facial measurements. Conclusion: This study inferred that while most of the measurements showed a positive correlation with the incisor width and canine width in the different face forms none of them were found to be significant.&nbsp

Boric acid as a potential substitute for conventional ethylene antagonists in mitigating postharvest flower senescence of Digitalis purpurea

In the floriculture industry, postharvest senescence is one of the glaring challenges restricting the marketability of cut flowers. Hence, maintaining good quality of cut flowers and extending flower longevity are considered to be the most crucial factors in the cut flower trade. Therefore, to gain better understanding of the specific physiological and biochemical aspects of petal senescence we conducted an experiment to evaluate the efficacy of Boric acid (BA) on flower longevity in excised flowers of Digitalis purpurea L. Isolated buds were harvested at stage IV i.e, 1 day before anthesis and divided into 5 sets, with one set of buds held in distilled water (DW) designated as control. The other 4 sets were supplemented with 24h pulse treatment of different concentrations of BA viz., 50, 100, 150 and 200 μM. The application of BA at 150 μM concentration was found to be most effective in increasing flower longevity by about 4 days as compared to control. The enhanced longevity coincided with higher values of floral diameter, fresh mass, dry mass and solution uptake. Flowers with delayed senescence also retained higher soluble proteins, sugars and phenols in addition to lower bacterial density compared to control. Moreover, this ameliorated flower longevity has also been shown to be positively associated with increased activities of various antioxidant enzymes viz., superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) and reduced activity of lipoxygenase (LOX)

Polyamines accentuate vase life by augmenting antioxidant system in cut spikes of Consolida ajacis (L.) Schur.

Postharvest senescence is one of the crucial challenges limiting the marketability of cut flowers. Pertinently, recent investigations implicate extensive role of polyamines in regulation of flower senescence. The present study was envisaged to test the efficacy of poylamines in preserving the postharvest quality of Consolida ajacis (C. ajacis) cut spikes. The cut spikes of C. ajacis were subjected to various treatments of polyamines viz, 4 mM Spermine (SPM), 6mM Putrescine (PUT) and 6 mM Spermidine (SPD). A separate set of spikes held in distilled water represented the control. Our results authenticate a significant improvement in vase life of cut spikes of C. ajacis as compared to control. The increment in vase life was commensurate with the higher concentration of sugars, proteins and phenols in the tepal tissues. Polyamines amplified the activity of various antioxidant enzymes viz, superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) to overcome the deleterious effects of reactive oxygen species (ROS). The membrane outflow of tepal tissues was profoundly reduced due to attenuated lipoxygenase (LOX) activity. These findings reveal conspicuous role of polyamines particularly SPM in modulation of flower senescence in cut spikes of C. ajacis

Genetic diversity analysis in the Hypericum perforatum populations in the Kashmir valley by using inter-simple sequence repeats (ISSR) markers

Assessment of genetic variability among the Hypericum perforatum populations is critical to the development of effective conservation  strategies in the Kashmir valley. To obtain accurate estimates of genetic diversity among and within populations of H. perforatum, inter-simple sequence repeats (ISSR) markers were used. The study was aimed to check, whether ISSR fingerprinting may be a useful tool for studying genetic variations among H. perforatum populations in the Kashmir valley (India). A total of 15 ISSR primers were tested with the 20 genotypes of H. perforatum. The ten informative primers were selected and used to evaluate the degree of polymorphism and genetic relationships within and among all the H. perforatum populations. ISSR of 20 genotypes analysis yielded 98 fragments that could be scored, of which 71 were polymorphic, with an average of 7.1 polymorphic fragments per primer. Number of amplified fragments varied in size from 150 to 1650 bp. Percentage of polymorphism ranged from 60% to a maximum of 100%. Resolving power ranged from a minimum of 7.7 to a maximum of 14.3. Shannon indexes ranges from 0.166 to 0.389 with an average of 0.198 and Nei’s genetic diversity (h) ranges from 6.98 to 9.8. Estimated value of gene flow (Nm = 0.579) indicated that there was limited gene flow among the populations. The genetic diversity (Ht) within the population of 0.245 was clearly higher than that of among population genetic diversity (Hs= 0.115), indicating an out-crossing predominance in the studied populations. Analysis of molecular variance by ISSR markers indicated that over half of the total variation in the studied populations (58%) could be accounted for by differences among the 8 divisions, with a further 42% being accounted for by the variation among populations within a division.The dendrogram grouping the populations by unweighted pair-group method with arithmeticaverages (UPGMA) method revealed eight main clusters. In conclusion, combined analysis of ISSR markers and hypericin content is an optimal approach for further progress and breeding programs.Keywords: Hypericum perforatum (St. John's Wort), inter-simple sequence repeats (ISSR) markers, unweighted pair-group method with arithmetic averages (UPGMA), Nei’s genetic diversityAfrican Journal of Biotechnology, Vol. 13(1), pp. 18-31, 1 January, 201

Enhancement of magnetic and dielectric properties of Ni0.25Cu0.25Zn0.50Fe2O4 magnetic nanoparticles through non-thermal microwave plasma treatment for high-frequency and energy storage applications

Spinel ferrites are widely investigated for their widespread applications in high-frequency and energy storage devices. This work focuses on enhancing the magnetic and dielectric properties of Ni0.25Cu0.25Zn0.50 ferrite series through non-thermal microwave plasma exposure under low-pressure conditions. A series of Ni0.25Cu0.25Zn0.50 ferrites was produced using a facile sol-gel auto-ignition approach. The post-synthesis plasma treatment was given in a low-pressure chamber by sustaining oxygen plasma with a microwave source. The structural formation of control and plasma-modified ferrites was investigated through X-ray diffraction analysis, which confirmed the formation of the fcc cubical structure of all samples. The plasma treatment did not affect crystallize size but significantly altered the surface porosity. The surface porosity increased after plasma treatment and average crystallite size was measured as about similar to 49.13 nm. Morphological studies confirmed changes in surface morphology and reduction in particle size on plasma exposure. The saturation magnetization of plasma-exposed ferrites was roughly 65% higher than the control. The saturation magnetization, remnant magnetization, and coercivity of plasma-exposed ferrites were calculated as 74.46 emu/g, 26.35 emu/g, and 1040 Oe, respectively. Dielectric characteristics revealed a better response of plasma-exposed ferrites to electromagnetic waves than control. These findings suggest that the plasma-exposed ferrites are good candidates for constructing high-frequency devices.Web of Science1519art. no. 689

Association of high immunohistochemical expression of minichromosome maintenance 3 with human oral squamous cell carcinoma—a preliminary study

Background: Oral squamous cell carcinoma (OSCC) may arise from premalignant oral lesions (PMOL) in most cases. Minichromosome maintenance 3 (MCM3) is a proliferative marker that has been investigated as a potential diagnostic biomarker in the diagnosis of oral cancer. Objectives: To evaluate the association of MCM3 expression, its clinicopathologic parameters and to identify snuff (also called naswar) as a potential risk factor for changes in MCM3 expression in PMOL and OSCC. Methodology: Immunohistochemistry (IHC) of MCM3 was performed on 32 PMOL, 32 OSCC and 16 normal controls after optimization of IHC methodology. Histoscore (0–300) was used as a scoring system and seven different cut-offs were identified for analyses. Data were analyzed using various statistical tests. Results: Among the seven cutoffs, 40% strong positive cells were found to be a better cut-off as they were associated with many pathological variables (Broder’s grade, Aneroth’s grade, and mitotic activity). The differential MCM3 expression in oral lesions (PMOL and OSCC) was statistically significant (p = 0.03). Moreover, MCM3 expression is raised with increased duration and frequency of snuff use. Conclusion: High MCM3 expression is associated with disease progression and is a potential indicator of malignant transformations from PMOL to OSCC. Moreover, the use of snuff is associated with MCM3 over-expression

Effect of Berberine Phytosome on reproductive, dermatologic, and metabolic characteristics in women with polycystic ovary syndrome: a controlled, randomized, multi-centric, open-label clinical trial

Background: Berberine is a poorly absorbed natural alkaloid widely used as nutraceutical to counteract diarrhoea and to lower cholesterol and hyperglycaemia. It has also been reported to reduce signs and symptoms of polycystic ovary syndrome (PCOS).Objective: To explore, through a multi-centric, randomized, controlled and prospective study, the possible role played by a form berberine that is more easily absorbed (Berberine Phytosome®, BP) in 130 Pakistani women with a diagnosis of PCOS and fertility problems due to menstrual and ovary abnormalities.Results: Ninety days of supplementation with BP, administered at 550 mg x2/die, determined (i) resumption of regular menstruation in about 70% of women (versus 16% in the control group; p < 0.0001), (ii) normalization of the ovaries anatomy in more than 60% of women (versus 13% in the control group; p < 0.0001), (iii) acne improvement in 50% of women (versus 16% in the control group; p = 0.0409) and (iv) hirsutism reduction in 14% of women (versus 0% in the control group; p = 0.0152). The metabolic and the hormonal profiles of the women in the two groups did not significantly differentiate at the end of the study. BP was well-tolerated and no specific side-effects were registered. Respectively after one, two and 8 years of trying, three women supplemented with BP became and are currently pregnant.Conclusion: Our study showed the positive effects of BP supplementation in women with PCOS and confirmed the high safety profile of this nutraceutical.Clinical Trial Registration:https://clinicaltrials.gov/, identifier NCT0548067
