Banana (Musa balbisiana) pseudostem 3D scaffolds have been developed here for primary eukaryotic cell and cell line culture as an economical, sustainable, eco-friendly alternative for surface-functionalized polymeric and plant tissue-based structures. Musa pseudostem 3D micro pattern scaffold (MPM-3Ds) developed by freeze-drying followed by ethylene oxide sterilization yielded 5.6ng of DNA per mg of tissue, confirming its extended decellularised state. Thermogravimetric analysis, contact angle measurement, uniaxial testing, and FTIR determined thermal stability, wettability, tensile strength, and surface functional groups respectively. Micro and macronutrients, sugars, and amino acids that naturally enrich MPM-3Ds were estimated using EDAX, HPLC, and biochemical analysis. The most important finding was, non-surface functionalized MPM-3Ds supported attachment, growth, and differentiation of human mesenchyme stem cells, human primary hepatocytes like cells, primary mouse brain cortical neurons, mouse fibroblast cells, and human pancreatic cancer cells. MPM-3Ds showed in vivo biodegradation and biocompatibility in a preliminary analysis in Sprague Dawley rats. These findings illuminate nature's power to nurture cells in the micropattern cradles of MPM- 3Ds that can support innovative research in stem cell differentiation, drug and cosmetic testing, and biosensor development leading to advanced biomedical research.
香蕉(Musa balbisiana)假茎3D支架是一种经济、可持续、环保的表面功能化聚合物和植物组织结构替代品,用于原代真核细胞和细胞系培养。通过冷冻干燥和环氧乙烷灭菌制备的Musa假茎3D微模式支架(MPM-3Ds)每mg组织中DNA含量为5.6ng,证实了其延长的脱细胞状态。热重分析、接触角测量、单轴测试和红外光谱分别测定了热稳定性、润湿性、抗拉强度和表面官能团。利用EDAX、HPLC和生化分析对天然富集MPM-3Ds的微量和宏量营养素、糖和氨基酸进行了估计。最重要的发现是,非表面功能化的MPM-3Ds支持人间充质干细胞、人原代肝细胞样细胞、小鼠原代脑皮质神经元、小鼠成纤维细胞和人胰腺癌细胞的附着、生长和分化。MPM-3Ds在Sprague Dawley大鼠体内表现出生物降解和生物相容性。这些发现阐明了大自然在MPM- 3Ds微模式摇篮中培育细胞的能力,可以支持干细胞分化、药物和化妆品测试以及生物传感器开发方面的创新研究,从而促进先进的生物医学研究。

The exact origin of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) responsible for unleashing the pandemic Corona Virus Disease (Covid-19) is still not established unambiguously. The intermediate and reservoir hosts of SARS-CoV-2 need to be identified with clarity and how the disease exploded into a pandemic, inevitability needs urgent scientific answers to contain and prevent future pandemics and crises. This perspective provides awareness of the peculiar features of SARS-CoV-2 and inspects the gaps in the natural zoonotic origin of the pandemic.

On account of the increasing demand for valuable herbal products, an attempt was made to produce a functional fermented Ethanol from Amla. This study investigates the potential of ethanol production from Amla (Emblica officinalis Gaertn). In the present study, Amla juice was extracted, filtered, fermented and it shows a suitable medium for the growth of Saccharomyces cerevisiae on yeast peptone dextrose medium for the production of ethanol. Ethanol was separated by fractional distillation and then estimated at 4, 6, 8 and 10 days of the fermentation process by iodometric method for 30oC. The ethanol percentage estimated by the iodometric titration method was high on the 10th day, and it was found to be 1.63 gm% compared to all days. So, the outcome of this study reveals that amla fruit can be used as a crucial constituent for the yield of ethanol with a higher commercial value.

Nanoparticles (1-100 nanometres in size), products of nanotechnology, offer a modern way to transport anti-cancer drugs by acting as transporters of drugs into tumor cells, hence quenching tumor cell proliferation. Such nanoparticles may be formulated to bind to the tumor cell membrane or inhibit specific reactions of tumor biosynthetic pathway by gene repression, or directly bind to the active sites of essential enzymes in the biosynthetic pathway. Consequently, drugs are completely delivered to the desired cancerous cells without system interference. Liposomal doxorubicin and albumin-bound paclitaxel are two examples of nanotechnologically developed drugs for treating cancer. Modern knowledge of nanotechnology opens up new opportunities for innovative research on cancer therapies and administration and helps minimize harm to healthy cells. This review focuses on the doses and routes of administration of these chemotherapeutic agents used in treating cancers.
纳米粒子(1-100纳米大小)是纳米技术的产物,它作为药物的转运体进入肿瘤细胞,从而抑制肿瘤细胞的增殖,为抗癌药物的运输提供了一种现代方式。这类纳米颗粒可配制成结合肿瘤细胞膜或通过基因抑制抑制肿瘤生物合成途径的特定反应,或直接结合生物合成途径中必需酶的活性位点。因此,药物完全被输送到所需的癌细胞而不受系统干扰。阿霉素脂质体和白蛋白结合紫杉醇是纳米技术开发的治疗癌症药物的两个例子。纳米技术的现代知识为癌症治疗和管理的创新研究开辟了新的机会,并有助于尽量减少对健康细胞的伤害。本文综述了用于治疗癌症的这些化疗药物的剂量和给药途径。

It has been established that providing comparable and standard environmental conditions to house experimental rats is of high importance. However, there is growing evidence that rats prefer higher temperatures owing to their thermoneutral zone that lies between 28-34°C. This experiment validates the stress levels of Wistar rats of both sexes housed in conventional conditions about 24-31°C and a relative humidity of 70-92% in a tropical animal facility when compared to rats housed in controlled temperatures of 20-24°C with humidity maintained between 30-70%. Adequate air-changes to maintain ammonia-free environment was provided with a power-exhaust system in a conventional setup and with the individually ventilated caging system in the environmentally controlled group. To assess stress, faecal corticosteroid metabolite assay was done in naïve animals and in a set of animals that underwent retro-orbital bleeding under general anaesthesia. Mothering ability, fecundity and preweaning mortality were also compared between animals housed in two different conditions. Results showed no differences in stress hormone levels between the groups. However, faecal weights differed between males and females in both naïve and orbital bled groups. Animals housed in controlled environment clearly had better breeding data with lesser preweaning mortality in comparison to the conventionally housed rats. Further studies are required to elucidate whether the results are comparable when conducted during all seasons of the year at different locations across the globe.
为实验大鼠提供可比较的标准环境条件具有重要意义。然而,越来越多的证据表明,老鼠喜欢更高的温度,因为它们的热中性区在28-34°C之间。本实验验证了在24-31°C、相对湿度70-92%的常规条件下饲养的Wistar大鼠与在20-24°C、湿度30-70%的控制条件下饲养的Wistar大鼠的应激水平。在常规装置中采用动力排气系统,在环境控制组中采用单独通风笼系统,以提供足够的换气以维持无氨环境。为了评估应激,在naïve动物和一组在全身麻醉下眶后出血的动物中进行了粪便皮质类固醇代谢物测定。还比较了饲养在两种不同条件下的动物的母性、繁殖力和断奶前死亡率。结果显示,两组之间的应激激素水平没有差异。然而,在naïve和眼眶出血组中,男性和女性的粪便重量不同。与常规饲养的大鼠相比,在受控环境中饲养的大鼠显然有更好的繁殖数据和更低的断奶前死亡率。需要进一步的研究来阐明在一年中的所有季节在全球不同地点进行的结果是否具有可比性。

In India, rice is the most significant crop in terms of the total area of cultivation and fertilizers. Distributed in 44.7 million hectares, it accounts for 31.8% (5.34 million tons) of the net use of the chemical fertilizer. Continuously using chemical fertilizers in agricultural production poses a severe environmental risk. The cost of chemical fertilizers is expensive and contributing to less crop yield. There is a need to adopt alternatives for chemical fertilizers in paddy fields. Cyanobacteria are abundant in paddy fields, and it presents remarkable contribution in producing the rice crop. It fixes atmospheric nitrogen, increases the accessibility of available phosphorus, and produces innumerable plant growth-promoting factors. It requires sunlight as the source of energy for carbon and nitrogen fixation in the soil. It represents remarkable potential as a biofertilizer and thereby decreases fuel demand for chemical fertilizer production. Cyanobacterial biofertilizers are inexpensive, simple to use, and do not harm the environment. This review focuses on the potential application of cyanobacterial biofertilizers in paddy fields.
在印度,就种植面积和肥料而言,水稻是最重要的作物。分布在4470万公顷,占化肥净使用量的31.8%(534万吨)。在农业生产中持续使用化肥造成了严重的环境风险。化肥价格昂贵,导致作物减产。在稻田里有必要采用化肥的替代品。蓝藻在水田中分布广泛,在水稻生产中发挥着重要作用。它固定了大气中的氮,增加了有效磷的可及性,并产生了无数的植物生长促进因子。它需要阳光作为土壤中碳和氮固定的能量来源。它代表了作为生物肥料的巨大潜力,从而减少了化肥生产的燃料需求。蓝藻生物肥料价格低廉,使用简单,对环境无害。本文综述了蓝藻生物肥料在水田中的应用前景。

RiboNucleic Acid (RNA) occupies the center position in the central dogma of molecular biology. These are the nucleotide with a ribose sugar and are found either in linear or circular form. The linear RNAs are of different types and include ribosomal RNA (rRNA), messenger RNA (mRNA), transfer RNA (t-RNA), small nuclear (snRNA) RNA, and very small/micro RNA (microRNAs). The circular (circRNA) RNA is a group of noncoding RNA, stable molecules, established recently and linked with the regulation of different genes, RNAs including microRNAs. The current understanding of these molecules suggests that these circRNAs are fairly conserved and show tissue-specific expression patterns. These molecules are connected with different pathogenic conditions and associated with verities of diseases, including cancer. CircRNAs are thus contributing to tumorigenesis, and these molecules show the potential to become future predictive biomarkers for diagnosis, prognosis and even can be targeted in personalized therapy. Hence, these bio-molecules will get exposed frequently, and their new cellular role will emerge, soon. This review outlines the current trend, limitations, and future potential of circRNA in cancer research.

The concepts in immunology and techniques in histology have come together in a novel way to create a pioneering discipline known as ImmunoHistoChemistry (IHC), to discover new ways in detecting cell and tissue antigens related to amino acids, proteins and infectious agents by using labeled antibodies. These amalgamation techniques are applied in the disciplines of endocrinology, entero-biology, neurobiology, pathology, tumor biology and pharmaceutical research as a diagnostic tool. The simultaneous advancements in the field of imaging techniques further assisted and widened the application of IHC in molecular studies, thereby facilitating the development of novel therapeutic strategies. This paper attempts to discuss the different aspects of gastro-intestinal tract in relation to its cellular diversity, cellular differentiation, physiology and pathology, through the application of IHC methods.

Recent studies have shown that the progression of SARS-CoV-2 is associated with human genetic factors. Many patients have shown diverse clinical symptoms based on their age, sex, ABO blood type, underlying medical conditions, HLA system, and viral variants found in their samples. SARS-CoV-2 is considered more transmissible with higher morbidity rates as compared to the previous SARS outbreak. Several case studies have supported the direct relation of cardiovascular and pulmonary fatalities related to ACE2 polymorphisms during COVID-19 infection. SARS-CoV-2 mutants and human genome polymorphisms are vital predictive markers in finding a cure for this pandemic. This review focuses on some of the critical genetic factors of the host that affect the array of immunological responses as a result of COVID-19 infection among individuals.
最近的研究表明,SARS-CoV-2的进展与人类遗传因素有关。许多患者表现出不同的临床症状,这取决于他们的年龄、性别、ABO血型、潜在的医疗条件、HLA系统和样本中发现的病毒变异。与之前的SARS疫情相比,SARS- cov -2被认为更具传染性,发病率更高。一些案例研究支持COVID-19感染期间与ACE2多态性相关的心血管和肺部死亡的直接关系。SARS-CoV-2突变体和人类基因组多态性是寻找这场大流行治愈方法的重要预测指标。本文综述了影响个体COVID-19感染后一系列免疫反应的宿主的一些关键遗传因素。

The aim of The Applied Biology & Chemistry Journal (TABCJ) is to be a focus for communication in research on the application of biological, biomedical and chemical sciences for studying, analyzing and understanding biological problems. Although the primary purpose of TABCJ is to offer a journal where cutting-edge research of broad interest may be published rapidly, without compromising on the quality, the additional features including avant-garde reviews will extend the scope of the journal by continuing its role beyond the reporting of research results.
《应用生物与化学杂志》(TABCJ)的宗旨是成为研究、分析和理解生物问题的应用生物学、生物医学和化学科学的研究交流的焦点。虽然TABCJ的主要目的是提供一份可以快速发表广泛关注的前沿研究的期刊,而不影响质量,但包括前卫评论在内的附加功能将通过继续其在报告研究结果之外的作用来扩展期刊的范围。
