Molecular diagnostic assay for pre-harvest detection of Tilletia indica infection in wheat plants

The current study describes a new diagnostic method for the rapid and accurate detection of Tilletia indica, the pathogen accountable for causing Karnal bunt (KB) disease in wheat. This method uses quantitative real-time polymerase chain reaction (qPCR) and a primer set derived from glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene of T. indica to identify the presence of the pathogen. The qPCR assay using this primer set was found highly sensitive, with a limit of detection (LOD) value of 4 pg of T. indica DNA. This level of sensitivity allows for the detection of the pathogen even in cases of different growth stages of wheat, where no visible symptoms of infection on the wheat plants can be seen by naked eyes. The study also validated the qPCR assay on ten different wheat cultivars. Overall, this study presents a valuable molecular tool for rapid, specific and sensitive detection of KB fungus in wheat host. This method has practical applications in disease management, screening of wheat genotypes against KB and can aid in the development of strategies to mitigate the impact of Karnal bunt disease on wheat production

Stochastic seismic response of building with shape memory alloy damper

The present study focuses on the estimation of response of building structure supplemented with the superelastic shape memory alloy (SMA) damper under the stochastic seismic excitation. To this end, the stochastic response has been determined using the stochastic linearization method under random earthquakes and the control efficiency of the SMA damper is compared with the yield damper. As the response output, top floor root mean square (rms) acceleration and displacement are presented here in this study. Response analysis results show the presence of optimal values of damper strength which minimizes the responses. As observed, in this optimal condition of damper strength, compared to the yield damper, the SMA damper provided 17 % and 49 % improvements in the values of top floor rms acceleration and displacement. In the end, the parametric study has been performed under the varying strength and stiffness of the damper, time period of the structure, and earthquake excitation to establish the superior control efficiency of SMA damper over yield damper

Prevalence, drug susceptibility pattern of Klebsiella pneumoniae in women with urinary tract infection

Background- Urinary tract infection (UTI) is an infection in which bacteria enters the tract and cultivate in the urinary tract i.e. the kidneys, ureters, bladder, and urethra. It is a common type of infection affecting females. UTI in case of K. Pneumoniae (gram – bacteria) is symptomatic with signs of increase in urinary frequency, urgency, suprapubic discomfort, and dysuria are all common symptoms.Materials and Methods- We recruited 80 female patients diagnosed with UTI of different ages for the study. The study population was female patients aged 18-45yrs, n=50 (group 1) and 55-85yrs, n=30 (group 2) who were hospitalized for symptoms of urinary tract infections. Midstream urine is collected in sterile containers. Samples were treated within 2 hours of collection in cysteine-lactose electrolyte deficiency (CLED) medium. Colony count, morphology, Gram stain, and biochemical characteristics were used to identify UTI-positive isolates. The disc diffusion method was used to test antibiotic susceptibility in both age groups, and the results were compared.&nbsp

Synthesis, biological evaluation and corrosion inhibition studies of transition metal complexes of Schiff base

Abstract Background The transition metal complexes formed from Schiff base is regarded as leading molecules in medicinal chemistry. Because of the preparative availability and diversity in the structure of central group, the transition metals are important in coordination chemistry. In the present work, we have designed and prepared Schiff base and its metal complexes (MC 1 –MC 4 ) and screened them for antimicrobial, anticancer and corrosion inhibitory properties. Methodology The synthesized metal complexes were characterized by physicochemical and spectral investigation (UV, IR, 1H and 13C-NMR) and were further evaluated for their antimicrobial (tube dilution) and anticancer (SRB assay) activities. In addition, the corrosion inhibition potential was determined by electrochemical impedance spectroscopy (EIS) technique. Results and discussion Antimicrobial screening results found complexes (MC 1 –MC 4 ) to exhibit less antibacterial activity against the tested bacterial species compared to ofloxacin while the complex MC 1 exhibited greater antifungal activity than the fluconazole. The anticancer activity results found the synthesized Schiff base and its metal complexes to elicit poor cytotoxic activity than the standard drug (5-fluorouracil) against HCT116 cancer cell line. Metal complex MC 2 showed more corrosion inhibition efficiency with high Rct values and low Cdl values. Conclusion From the results, we can conclude that complexes MC 1 and MC 2 may be used as potent antimicrobial and anticorrosion agents, respectively

Sperm Cell Driven Microrobots-Emerging Opportunities and Challenges for Biologically Inspired Robotic Design

With the advent of small-scale robotics, several exciting new applications like Targeted Drug Delivery, single cell manipulation and so forth, are being discussed. However, some challenges remain to be overcome before any such technology becomes medically usable; among which propulsion and biocompatibility are the main challenges. Propulsion at micro-scale where the Reynolds number is very low is difficult. To overcome this, nature has developed flagella which have evolved over millions of years to work as a micromotor. Among the microscopic cells that exhibit this mode of propulsion, sperm cells are considered to be fast paced. Here, we give a brief review of the state-of-the-art of Spermbots - a new class of microrobots created by coupling sperm cells to mechanical loads. Spermbots utilize the flagellar movement of the sperm cells for propulsion and as such do not require any toxic fuel in their environment. They are also naturally biocompatible and show considerable speed of motion thereby giving us an option to overcome the two challenges of propulsion and biocompatibility. The coupling mechanisms of physical load to the sperm cells are discussed along with the advantages and challenges associated with the spermbot. A few most promising applications of spermbots are also discussed in detail. A brief discussion of the future outlook of this extremely promising category of microrobots is given at the end

Association of vitamin-D with hypothyroidism in adult female patients in north Indian population

Background: Thyroid disorder is found to be most commonly occurring endocrine disorder in females. Thyroid hormones have an imperative position in metabolic methods in human body, and several physiological and pathological stimuli are known to influence thyroid metabolism. The increased incidence of hypovitaminosis D was diagnosed in population with hypothyroidism. Objective: To check the relation of Vitamin D in adult female patients diagnosed with hypothyroidism. Method: We recruited 60 patients and divided these patients into two groups, Group-1- Hypothyroidism patients (n=30) and Group-2- Control patients (n=30). Thyroid-Stimulating Hormone (TSH), total Triiodothyronine (T3), total Thyroxine (T4), and Vitamin D levels were estimated by automated method in Abbott ARCHITECT ci8200 machine. Results: In the present study we found patients with hypothyroidism 73.3% (n=22) has low level of Vitamin D while 26.6% (n=8) of population have normal level of Vitamin D. We could not find significant association between Vitamin D and hypothyroidism (p>0.05). Conclusion: Our study concluded that hypothyroidism has no significant role in lowering the levels of Vitamin D but we also emphasize the fact that Vitamin D should be done as routine investigation in healthy as well as hypothyroidism patients as its value was also less in control subjects
