The transport of objects in a warehouse is an indispensible but time consuming task, and is therefore the focus of extensive research. This paper presents a system that autonomously retrieves boxes placed in shelves according to the part number fed in the system by the user. The system utilizes a modified implementation of the A<SUP>*</SUP> algorithm to determine the shortest path for retrieving the objects. A maximum of three objects can be retrieved in one round by the robot. After retrieval, the objects are delivered to a delivery station. Line tracking sensors are used for robot navigation. Telescoping arms mounted on the robot are used to retrieve objects from the shelves. The guidance algorithm and Graphic User Interface (GUI) have been implemented using MATLAB® and the robot has been designed using SolidWorks®.

P63 is a gene product required in cell cycle regulation which plays vital roles in tumor differentiation. Aims of the present study were to assess the frequency, pattern, sensitivity and specificity of two p63 protein clones P63 4A4 and P63 4A4+Y4A3 in squamous cell carcinomas (SCCs). Thirty cases of head and neck region SCC diagnosed on the basis of H&E staining were examined along with 60 cases of head and neck region biopsies other than squamous cell carcinoma, negative on H&E staining, were taken as control. Immunostaining was performed on slides according to the Thermo Scientific UltraVision LP detection System. P63 4A4+Y4A3 clone is more sensitive 96.6% in comparison to 86% in P63 4A4 with having greater NPV of 98.3%. The results signify the importance of P63 4A4+Y4A3 marker over the old markers and may be used as a confirmatory marker of squamous cell carcinoma.

ObjectivePolycystic ovary syndrome is a diverse endocrine disorder characterized by hyperandrogenism and ovulatorydysfunction. Hyperandrogenism affects body morphology, resulting in excess weight (overweight or obesity). This study aimed to evaluate the efficacy of high-intensity interval training on serum testosterone levels, body fatpercentage, and level of physical activity among women with polycystic ovary syndrome. MethodsFifty participants were enrolled in the study and randomly allocated into two groups. Group A performed highintensityinterval training on alternate days per week (total of 12 weeks) and group B performed strength training onalternate days per week (total of 12 weeks). Baseline and 12th-week assessments included serum testosterone levels,body fat percentage using the skinfold method, and level of physical activity assessed using the International PhysicalActivity Questionnaire. ResultsAfter 12 weeks of intervention, both groups showed significant improvements in all the outcomes. However, groupA (high intensity interval training) showed statistically significant results compared to group B (strength training) inlowering serum testosterone levels (P=0.049) and body fat percentage (P=0.001) and increasing physical activity levels(P=0.006). ConclusionAfter 12 weeks of exercise, both exercises benefited the participants; however, high-intensity interval trainingspecifically was found to be a more effective exercise regimen than strength training in reducing serum testosteronelevels and body fat percentage and enhancing levels of physical activity in women with polycystic ovary syndrome. 영어

Crosstalk of Zn in Combination with Other Fertilizers Underpins Interactive Effects and Induces Resistance in Tomato Plant against Early Blight Disease

The present study was undertaken to evaluate the integrated effect of zinc (Zn) with other nutrients in managing early blight (EB) disease in tomato. A pot experiment was carried out with basal application of the recommended level of macronutrients [nitrogen, phosphorus and potassium (NPK)] and micronutrients [magnesium (Mg) and boron (B)] in bilateral combination with Zn (2.5 and 5.0 mg/kg) in a completely randomized deigned in replicates. Results revealed that interactive effect of Zn with Mg or B was often futile and in some cases synergistic. Zn with NPK yield synergistic outcome, therefore EB disease was managed significantly (disease incidence: 25% and percent severity index: 13%), which resulted in an efficient signaling network that reciprocally controls nutrient acquisition and uses with improved growth and development in a tomato plant. Thus, crosstalk and convergence of mechanisms in metabolic pathways resulted in induction of resistance in tomato plant against a pathogen which significantly improved photosynthetic pigment, total phenolics, total protein content and defense-related enzymes [superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL)]. The tremendous increase in total phenolics and PAL activity suggesting their additive effect on salicylic acid which may help the plant to systemically induce resistance against pathogen attack. It was concluded that interactive effect of Zn (5.0 mg/kg) with NPK significantly managed EB disease and showed positive effect on growth, physiological and biochemical attributes therefor use of Zn + NPK is simple and credible efforts to combat Alternaria stress in tomato plants.

A review of carbon-based materials and their coating techniques for biomedical implants applications

Hassan Sadia,Nadeem Aroosa Younis,Qaiser Hafsah,Kashif Amer Sohail,Ahmed Ammad,Khan Khushbukhat,Altaf Amna 한국탄소학회 2023 Carbon Letters Vol.33 No.4

Carbon-based materials have emerged as an excellent class of biomedical materials due to their exceptional mechanical properties, lower surface friction, and resistance to wear, tear, and corrosion. Experimental studies have shown the promising results of carbon-based coatings in the field of biomedical implants. The reasons for their successful applications are their ability to suppress thrombo-inflammatory reactions which are evoked as an immune response due to foreign body object implantation. Different types of carbon coatings such as diamond-like carbon, pyrolytic carbon, silicon carbide, and graphene have been extensively studied and utilized in various fields of life including the biomedical industry. Their atomic arrangement and structural properties give rise to unique features which make them suitable for multiple applications. Due to the specificity and hardness of carbon-based precursors, only a specific type of coating technique may be utilized for nanostructure development and fabrication. In this paper, different coating techniques are discussed which were selected based on the substrate material, the type of implant, and the thickness of coating layer. Chemical vapor deposition-based techniques, thermal spray coating, pulsed laser deposition, and biomimetic coatings are some of the most common techniques that are used in the field of biomaterials to deposit a coating layer on the implant. Literature gathered in this review has significance in the field of biomedical implant industry to reduce its failure rate by making surfaces inert, decreasing corrosion related issues and enhancing biocompatibility.
