Distribution and abundance of cirripede larvae (Cirripedia: Thoracica) in the northern Arabian Sea

Cirripede larvae obtained in the zooplankton samples of the North Arabian Sea Ecological and Environmental Research (NASEER) cruise I (January, 1992) have been studied for their distribution and abundance. They were collected in the northern Arabian Sea waters (22°51'N to 24°58'N, 60°05'E to 65°59'E). Thirty- two samples were taken at 18 stations. The maximum number of larvae were collected from a station near Indus cone (Sta. 8), whereas an off shore station (Sta. 37) and one near the Makran coast (Sta. 60) had poor representation. Regular coastal collections from Manora Channel (24°48'N, 66°59'E), during the study period of one year (1994), have been also included to supplement the NASEER samples. Only one naupliar stage (VI) and a cyprid stage were identified. Relative abundance in day and night samples were also studied

Description of stomatopod larvae from the Arabian Sea

The Northern Arabian Sea Ecological and Environmental Research (NASEER) Programme cruise I, January, 1992 and other collections from Manora Channel (Karachi) were examined. Six stages i.e. IV, VII, VIII, IX, X and XI of stomatopod larvae are recognized. Day samples talen in 1994 (January to December) from Manora Channel revealed the presence of only three specimens of stage IV. They all belong to the family Squillidae. Each stage is measured, described and illustrated. None of the stages could be correlated to their adults

miRNAs: Small but deadly

microRNAs (miRNAs) are unique class of global gene regulators identified both in plants and animals. They can reduce protein levels of their target genes with a minor impact on the target genes mRNA. Levels of some miRNAs are found altered in cancers, so we might expect these regulatory molecules to be involved in the development of different carcinomas. The differential expression of certain miRNAs in various tumors might become a powerful tool to aid in the diagnosis and treatment of cancers. The precise biological roles of most miRNAs are still poorly understood and therefore, this review is an attempt to highlight the role and connections of human miRNA with different aspects of cancers.Key words: microRNA, cancer, tumour, metastasis, upregulation, miRNA

Pap smear screening in antenatal women: an opportunistic way to save life

Background: Cancer cervix is the most common genital tract malignancy encountered in developing countries. In India, first visit to the gynaecologist for most women is during pregnancy and it may be the only visit. Hence, prenatal care offers an excellent opportunity to implement cervical screening in patients of young age, especially in women who do not seek routine health care. Therefore, this study was conducted to know the prevalence of abnormal Pap smear among the ante-natal women and to evaluate the result in relation to various risk factors.Methods: Cross sectional observational study conducted on 425 ante-natal women attending the antenatal clinic using questioner addressing various socio-demographic variables. Measures of central tendency calculated and result was tabulated by using chi-square test.Results: Maximum number of cases in our study was NILM i.e.314 (74%) followed by 68 cases of Candida (16%), 30 cases of Bacterial vaginosis (7.1%) and 10 cases of Trichomonas vaginalis (2.4%). Only 3 cases of abnormal Pap smear was reported i.e. 2 of ASCUS and 1 of LSIL. Thus, prevalence of abnormal Pap smear was 0.7%.Conclusions: In country like India where organised screening programme are not available, as well as the awareness and uptake of available services by the target population is also poor; screening in pregnancy is worthwhile and may be a viable option to reduce the burden of cervical carcinoma.

FTIR and XRD evaluation of magnesium doped hydroxyapatitesodium alginate powder by precipitation method

Composites material were developed to acquire the desired material properties for biomedical applications in the recovery of defect bone by using Mg-doped HA/SA. Hydroxyapatite (HA) is the major constituent and essential component in bone and teeth. The stability of Mg-doped HA/SA is influenced by starting precursor powders, preparation condition and method of preparing the samples for implant materials. The precipitation method was employed to prepare Mg-doped HA/SA powders by varying the composition of Mg at temperature 1300°C. The influence of Mg-doped HA/SA on phase composition, chemical structure and a functional group at various weight percentages (0.5wt%-1.5wt %) were accomplished through X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) analyses. Based on the XRD and FTIR analyses, there is the presence of different peaks intensity and adsorption bands which indicates the shifted of peaks due to the doping process and a chemical interaction were observed between the inorganic and organic phase. Furthermore, the transformation of β-TCP due to increase in sintering temperatures are caused by the presence of magnesium ions. The OHstretching bands of HA/SA are traced by FTIR that identified the decomposition of Mg-doped HA/SA

Clarity on frequently asked questions about drought measurements in plant physiology

Drought, or environmental water deficit, is one of the major limiting factors affecting crop yield worldwide. Development of drought-resistant crop cultivars is a major research and development challenge. Drought-related experiments are performed usually to understand the physiological and molecular mechanisms of drought tolerance. Such experiments are also performed to develop transgenics or crop cultivars resistant to drought using physiological and molecular markers. Drought-related experiments are executed in growth chambers, growth rooms, greenhouses, wire net-houses or in research fields. However, a plethora of research publications investigating drought has experimental weaknesses and flaws with respect to the approaches used. It is, therefore, necessary for agronomists, plant breeders, plant physiologists, and molecular biologists to be aware of common pitfalls and have the minimum knowledge required for drought measurements. There are several questions that are often asked by students and professionals alike, and these questions often appear on academic social media platforms. This article summarises the questions we have been asked about drought measurements personally and those asked on academic social media platforms. It also addresses ambiguous questions arising from published literature. We aim to respond to them to the best of our knowledge in order to provide a reference point for a beginner interested in performing drought-related experiments. This article will only focus on drought in relation to plant physiology and will not cover the usage of the term or drought measurements in other contexts

Effect of plant growth promoting rhizobacteria on root morphology of Safflower (Carthamus tinctorius L.)

Rooting characteristics significantly affect the water-use patterns and acquirement of nutrient for any plant species. Plant growth promoting rhizobacteria improve the plant growth by a variety of ways like the production of phytohormones, nitrogen fixation, phosphate solubilization and improvement in root morphology etc, and are also useful in cutting down the cost of chemical fertilizers. The present investigation was carried out to determine the comparative effect of plant growth promoting rhizobacteria (PGPR), Azospirillum brasilense, Azotobacter vinelandii and Pseudomonas stutzeri, either alone or in combination with different doses of chemical fertilizers [full dose (Urea at 60 kg ha-1 and DAP at 30 kg ha-1), half dose (Urea 30 kg ha-1 and DAP 15 kg ha-1) and quarter dose (Urea 15 kg ha-1 and DAP 7.5 kg ha-1)] on root morphology and root distribution pattern of safflower (Carthamus tinctorius L.) viz. cvv. Thori and Saif-32 in the soil. The PGPR were applied as seed inoculation at 106 cells/ml prior to sowing. P. stutzeri either alone or in combination with full dose of chemical fertilizers, was highly effective in increasing the root area in cv. Saif-32, whereas, the percent increase due to A. brasilense was comparable to that of treatment with full dose of chemical fertilizers. P. stutzeri inoculation resulted in significantly higher root length in both the cultivars. Significantly, higher root width (54%) of cv. Thori was observed in treatment receiving inoculation with A. vinelandii and supplemented with half dose of chemical fertilizers, whereas maximum root width of cv. Saif-32 was recorded in treatment supplemented with half dose of chemical fertilizers. It is inferred that PGPR inoculation especially those of A. brasilense and P. stutzeri either alone and more so in combination with half dose of chemical fertilizers, are highly effective in improving root morphology and growth in safflower.Key words: Root area, safflower, plant growth promoting rhizobacteria (PGPR), root growth, chemical fertilizers

Multilingual advertising in the linguistic landscape of Seoul

This study examines commercial signs in arguably the two most visited tourism districts in Seoul, namely Myeongdong and Insadong. It focuses on beauty and food businesses and analyzes featured languages and their content and roles in signage. This article argues that business types, specialized marketing focus, and intended sales pitch influence business owners’ linguistic choices. The findings of the study suggest that the beauty industry relies heavily on English in general, but the power of K‐Beauty popularized by ‘Hallyu’ (The Korean Wave) beyond Korea inevitably invites linguistic accommodation in the form of using Chinese and Japanese. In general, the business category of beauty features a more prevalent use of English than the gastronomic business in this study. Moreover, as an area specializing in traditions and cultural heritage, Insadong shows more signs exclusively in Korean than in Myeongdong.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151302/1/weng12427_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151302/2/weng12427.pd

Combining ability analysis for various yield and quality traits in rice (Oryza sativa L.)

An investigation was undertaken to assess the combining ability for yield and quality traits in rice. Three WA cytoplasmic male sterile lines of rice i.e., IR-58025A, IR-68897A and Pusa 6A were crossed with six restorer genotypes i.e., Sanwal Basmati, Pusa Sugandh-2, Pusa Sugandh-3, Pusa Sugandh-5, Pusa 2517-2-51-1 and HURJM- 59221 in line x tester design to generate 18 hybrids. Among the female parents, IR-58025A revealed significant desirable value of GCA effect for yield per plant and most of the quality traits. Among the pollen parents, Pusa Sugandh-3 revealed significant desirable value of GCA effect for most of the yield traits. However, Pusa Sugandh-5 revealed significant desirable value of GCA effect for most of the quality traits. Pusa 6A x Pusa Sugandh-2 evinced the highest significant value of SCA effect for grain yield followed by IR-58025A x Pusa Sugandh-5. However, IR- 68897A x Pusa 2517-2-51-1 followed by IR-58025A x Sanwal Basmati revealed the significant desirable value of SCA effect for most of the quality traits. For both yield and quality traits, IR-58025A x Pusa Sugandh-5, IR-68897A x HUR-JM-59221 and Pusa 6A x Pusa Sugandh-2 were found to be relatively better performing. Thus, present study aims to develop hybrids performing better for both yield and quality traits
