Background: In developing countries, perinatal hypoxia is still a leading cause of mortality and disability. In 2011, the infant mortality rate dropped from 92 per 1000 live births in 1991 to 43 per 1000 live births. However, neonatal mortality in Bangladesh remains high, accounting for more than half of all deaths under the age of five and more than two-thirds of infant mortality. As a result, any qualities that can operate as a risk factor for prenatal asphyxia can be quite beneficial. The aim of the study was to observe the maternal characteristics of perinatal asphyxia in full-term pregnancies. Material Methods: This cross-sectional descriptive study was conducted at the Department of Obstetrics and Pediatrics, Rangpur Medical Collage, and Hospital, Rangpur, Bangladesh. The study duration was 2 years, from January 2012 to December 2013. The study was conducted with a total of 60 cases of birth asphyxia, who were delivered or admitted into the study hospital. Results: In 70% of cases, the mother was Primipara. Among the neonates, 61.67% were male, and 38.33% were female. Only 33% of the case neonates had received regular antenatal check-ups, while 55% had irregular check-ups, and 11.67% had no antenatal checkups. According to the grading of asphyxia, 51.67% of neonates had moderate asphyxia, 20% had mild asphyxia, and 28.33% had severe asphyxia. The mean serum sodium value in mild, moderate, and severe asphyxia were 135.33, 123.42, and 121.53 mmol/L respectively. Mean serum potassium values were 4.11, 4.86, and 5.51 mmol/L respectively. Mean serum creatinine 0.72, 1.00, and 1.83 mg/dl respectively. Mean blood urea levels were 36.17, 58.97, and 88.06 mg/dl respectively. A significant difference was observed between the mean values of serum electrolytes and patients’ asphyxia grade. Conclusion: The study findings revealed that birth asphyxia was more common among vaginal deliveries and irregular or no neonatal care cases. Primipara patients had a higher likelihood of neonatal asphyxia. Serum electrolyte levels varied significantly based on the grade of asphyxia.

Internet-of-Everything (IoE) is defined as networked connections of things, people, data, and processes. IoE nodes, preferably shaped as printed flexible systems, serve as the frontier outpost of the Internet and comprise devices to record and regulate states and functions. To power distributed IoE nodes in an ecofriendly manner, a technology to scavenge energy from ambience and self-powered devices is developed. For this, piezoelectricity is regarded as a key property; however, the current technology typically based on polyvinylidene difluoride (PVDF) copolymers is expensive and produced via toxic protocols. We report piezoelectric characteristics of electrochemically poled cellulose nanofiber (CNF) thin films processed from water dispersions. Poling these films under humid conditions causes breaking and reorientation of CNF segments, which results in enhanced crystal alignment rendering the resulting material piezoelectric. Generators based on poled CNF show similar piezoelectric voltage and coefficient, here measured as d(33) = 46 pm V-1, to devices including PVDF copolymer layers of similar thickness. Our findings promise low-cost and printable ecofriendly piezoelectric-powered IoE nodes.

Background: Zinc oxide Nanoparticles can be prepared by various chemical, physical, and biological methodologies. But biological approach is easier than the other methods and also eco-friendly. Purpose of study: Plant-mediated amalgamation of Zinc oxide nanoparticles is promising contrast to traditional method of physical and chemical synthesis. Method: In the current research work, Zinc oxide nanoparticles are synthesized by using Leaf extracts of Manilkara Zapota plant. Green synthesis was done utilizing the aqueous solution of Manilkara Zapota leaf extract as reducing agent and Zinc acetate salts along with Sodium hydroxide. Morphological, Structural and Antimicrobial properties of synthesized Zinc oxide nanoparticles were characterized using Scanning electron microscope, Fourier transform infrared analysis, Differential scanning calorimetry and Disc diffusion method. ' Results: Biologically synthesized nanoparticles of Manilkara Zapota leaf extract revealed significant Anti-bacterial and Anti-fungal activities. Cocnclusion: The organically incorporated nanoparticles by Manilkara Zapota can be utilized as antimicrobial agent against various pathogenic organisms.

The ranking of seeds represents remarkable transition phase for photosynthasis and sexual reproduction, this phase is complex & successful method for sexual reproduction in vascular plants. As we know that seed containe the genetic repository of past & potential for its perpetuation in the future. The dormancy in seeds induced by desciccation & the hormone abscisic acid (ABA) till the condition in growth become favorable. The well developed seeds eliminates requirement of water during sexual reproduction & allows fertilization events to occur over long distances. Germination of seeds in particular situation and season is determines the interaction between dormancy and relating factors like phytochemical development to give healthy bioactives, which strongly influence on the termination of dormancy or initiatin of germination and seedling in many plant species like photo-hormons, light, temperature, water, neutrients and mechanical cuse. Seeds of particular plants needs difreent pretreatment to give vigor seedlings even in production so far. The entiteled chapter represents amulgumation of agriculturists and life scientists. Recent significant progress has been endorsed in seed physiology to solve the practical issues constantly associated with the seeds. The aim & objective of this articale is to enlighten the reader, not only about the different aspects of the seed physiology it also includes the development of bioactive (secondary metabolites) in the healthy seeds. This resorce of pice will help researcher to sencitize about the type of healthy bioactive available in the shalls of seedlings. This could be the reason to isolate the biomolecules from a well evaluate seeds, seed evalution not only the sorce to get healthy crops in agricultural scince it also helps so for a phytochemist to get theuraputicaly active biomolecules, without destroying the nature, which could be the value added thought to combat with the burning issues associated with the existing situation (COVID Omicron, viral infection and all kinds of disorder associated with the immune system). Henceforth, endorsed personage to give real-time attention to plant propagation, particularly for indigenous tree species and seedling multiplication should be regarded as a primary need to make not only a sustainable environment but also become a treasure to fulfill the needs of industry application in the field of agriculture plus R & D.
