In this present work, the effect of variation of parts (pulp and peel) on photochemical 

compounds such as phenolics and flavonoids content of the banana flours were 

studied. The results exhibited that different varieties did exhibit significant differences 

on TPC as well as TFC which means that different sample yielded different values of 

TPC and TFC. The TPC was determined in ethanolic extracts of banana peel and pulp 

flour. The TPC was found to be about 0.40 mg/ml in banana peel and about 0.33

mg/ml in banana pulp. Thus, it is clear that the TPC was higher in the peel than in the 

pulp, while the total flavonoids content was determined in methanolic extracts of 

banana peel and pulp flour. The results showed that TFC was higher in banana peel 

(0.37 mg/ml) than in banana pulp (0.20 mg/ml). 

Key words: banana, catechol , quercetin, total flavonoids, total phenolics.

This research endeavor delved deeply into the potential protective efficacy of moringa extract in ameliorating renal impairments instigated by a high-fat dietary regimen in male rat models. The subjects were judiciously classified into six discrete cohorts, each comprising six individuals, with the subsequent allocation: Group 1 serving as the non-intervention control; Group 2 receiving a daily dose of 300 mg/kg body weight moringa extract (ME) spanning 8 weeks; Group 3 subjected to a sustained high-fat diet (HFD) throughout an 8-week interval; Group 4 exposed to a dual-modality involving an HFD and daily administration of 300 mg/kg bw ME for the identical duration; Group 5 subjected to the combined impact of an HFD and a daily 40 mg/kg bw dose of simvastatin (SIM) across 8 weeks; lastly, Group 6 subjected to a concurrent treatment approach involving an HFD, 300 mg/kg bw ME, and 40 mg/kg bw SIM, daily, over an 8-week period. Through an intricately orchestrated sequence of experiments, we embarked upon an expedition to unearth the Reno protective potential of moringa extract against dietary-induced nephrological impairment. Our findings offer an all-encompassing outlook on the synergy between dietary interventions and the innovative agents under scrutiny. This inquiry not only advances our comprehension of potential remedies for diet-associated renal adversities but also accentuates the emergence of moringa extract as a formidable contender in this domain. Our revelations illuminated that the application of a high-fat diet ushered in a substantial surge in malondialdehyde (MDA) levels, emblematic of heightened oxidative stress. This was concomitant with a marked depletion in glutathione (GSH), aggregate antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and glutathione reductase (GSH-Rd) levels. Conversely, the administration of moringa extract adeptly mitigated these adverse repercussions induced by the high-fat dietary regimen.

A smart home is a technologically equipped residence that proactively observes its residents and offers various services. It has emerged as a potential solution to support independent living for people with disabilities and older adults, while also relieving the burdens on family caregivers and healthcare providers. A fundamental aspect of smart homes is their capability to monitor daily living activities and ensure residents' safety by detecting changes in their routines. With the advancements in technology, modern smart homes are furnished with numerous low-power sensors, radios, and embedded processors that collaboratively process data to assess the home's state and the behaviors of its occupants. This article delves into the sensor technology employed in smart homes, with a particular focus on direct environment sensing and infrastructure-mediated sensing. It explores the strengths and limitations of different sensor technologies and discusses the challenges and opportunities from technical, and ethical perspectives.

AbstractIntroduction

The endemic species Nepeta cyrenaica Quézel & Zaffran, native to northeastern Libya, is valued as an important honey-bearing plant.

Objectives

This study was aimed to examine the micromorphology, phytochemistry, and bioactivity of in vitro-propagated N. cyrenaica for the first time.

Materials and Methods

The leaf indumentum was examined using light and scanning electron microscopy and further characterised for histochemistry. The chemical composition of essential oil (EO) was performed using GC-MS analysis, while dichloromethane (DCM), methanol (ME), ethanol (ET), and aqueous (AQ) extracts were analysed using qualitative and quantitative LC/MS analyses. The antioxidant activities of EO and extracts were assessed using three parallel assays, while enzyme-inhibiting effects were evaluated against four enzymes.

Results

The leaves bear various types of glandular trichomes, with lipophilic secretion predominating. The main EO component of EO was 1,8-cineole. A considerable number of phenolics and iridoids were tentatively identified in the ME extract. Quantitative LC/MS analysis confirmed that ferulic acid, rosmarinic acid, and epigallocatechin gallate were present in the highest amount in the extracts, in which three iridoids were also quantified. Although the ME extract contained the highest amount of polyphenolics and iridoids, the DCM extract showed the best overall biological potential. Additionally, EO exerted the strongest acetylcholinesterase and tyrosinase inhibition.

Conclusion

This study demonstrated that the endemic N. cyrenaica can be efficiently grown under in vitro conditions, where it develops various glandular trichomes that are thought to secrete and/or accumulate bioactive compounds with valuable medicinal potential.
