    Abstract A particular biological process known as wound healing is connected to the overall phenomena of growth and tissue regeneration. Several cellular and matrix elements work together to restore the integrity of injured tissue. The goal of the present review paper focused on the physiology of wound healing, medications used to treat wound healing, and local drug delivery systems for possible skin wound therapy. The capacity of the skin to heal a wound is the result of a highly intricate process that involves several different processes, such as vascular response, blood coagulation, fibrin network creation, re-epithelialisation, collagen maturation, and connective tissue remodelling. Wound healing may be controlled with topical antiseptics, topical antibiotics, herbal remedies, and cellular initiators. In order to effectively eradicate infections and shorten the healing process, contemporary antimicrobial treatments that include antibiotics or antiseptics must be investigated. A variety of delivery systems were described, including innovative delivery systems, hydrogels, microspheres, gold and silver nanoparticles, vesicles, emulsifying systems, nanofibres, artificial dressings, three-dimensional printed skin replacements, dendrimers and carbon nanotubes. It may be inferred that enhanced local delivery methods might be used to provide wound healing agents for faster healing of skin wounds.

    Abstract Communication is challenging for disabled individuals, but with advancement of brain-computer interface (BCI) systems, alternative communication systems can be developed. Current BCI spellers, such as P300, SSVEP, and MI, have drawbacks like reliance on external stimuli or conversation irrelevant mental tasks. In contrast to these systems, Imagined speech based BCI systems rely on directly decoding the vowels/words user is thinking, making them more intuitive, user friendly and highly popular among Brain-Computer-Interface (BCI) researchers. However, more research needs to be conducted on how subject-specific characteristics such as mental state, age, handedness, nativeness and resting state activity affects the brain's output during imagined speech. In an overt speech, it is evident that native and non-native speakers' brains function differently. Therefore, this paper explores how nativeness to language affects EEG signals while imagining vowel phonemes, using brain-map analysis and scalogram and also investigates the inclusion of features extracted from resting state EEG with imagined state EEG. The Fourteen-channel EEG for Imagined Speech (FEIS) dataset was used to analyse the EEG signals recorded while imagining vowel phonemes for 16 subjects (nine native English and seven non-native Chinese). For the classification of vowel phonemes, different connectivity measures such as covariance, coherence, and Phase Synchronous Index-PSI were extracted and analysed using statistics based Multivariate Analysis of Variance (MANOVA) approach. Different fusion strategies (difference, concatenation, Common Spatial Pattern-CSP and Canonical Correlation Analysis-CCA) were carried out to incorporate resting state EEG connectivity measures with imagined state connectivity measures for enhancing the accuracy of imagined vowel phoneme recognition. Simulation results revealed that concatenating imagined state and rest state covariance and PSI features provided the maximum accuracy of 92.78% for native speakers and 94.07% for non-native speakers.

    Abstract Purpose: The goal of the present research was to isolate a biopolymer from Phaseolus vulgaris (P. vulgaris) and Zea mays (Z. mays) plants and used it to construct Resveratrol (RES)-loaded translabial films.
    Methods: Biopolymers were extracted from P. vulgaris and Z. mays seeds using a simple process. Separated biopolymers, sodium carboxymethylcellulose (SCMC) and tragacanth were subjected to formulation development by incorporating RES-loaded translabial films. The Fourier-transform infrared spectroscopy (FTIR), physical appearance, weight, thickness, folding endurance, swelling index, surface pH, percent moisture absorption, percent moisture loss, vapor transfer rate, and content uniformity of the translabial films were examined. The mucoadhesive, ex-vivo permeation, in vivo and stability studies, were performed.
    Results: The results showed that RES-loaded translabial films produced from P. vulgaris and Z. mays biopolymers exhibited exceptional mucoadhesive, stability, and permeation properties. Results revealed that the best formulations were prepared from a combination of biopolymer (P. vulgaris C or Z. mays C) with tragacanth. Formulations with tragacanth revealed good swelling and thus permeation profiles. In vivo release of TL 11 was found to be 24.05 ng/ml in 10 hours and it was stable enough at 45°C.
    Conclusion: This research suggested that RES-loaded translabial formulations can be potentially used for the treatment of Parkinson's disease with good patient compliance to geriatric and unconscious patients.

    Abstract Computer-based modelling and simulation are developing as effective tools for supplementing biological data processing and interpretation. It helps to accelerate the creation of dosage forms at a lower cost and with the less human effort required to conduct the work. This paper aims to provide a comprehensive description of the different computer simulation models for various drugs along with their outcomes. The data used are taken from different sources, including review papers from Science Direct, Elsevier, NCBI, and Web of Science from 1995-2020. Keywords like - pharmacokinetic, pharmacodynamics, computer simulation, whole-cell model, and cell simulation, were used for the search process. The use of computer simulation helps speed up the creation of new dosage forms at a lower cost and less human effort required to complete the work. It is also widely used as a technique for researching the structure and dynamics of lipids and proteins found in membranes. It also facilitates both the diagnosis and prevention of illness. Conventional data analysis methods cannot assess and comprehend the huge amount, size, and complexity of data collected by in vitro, in vivo, and ex vivo experiments. As a result, numerous in silico computational e-resources, databases, and simulation software are employed to determine pharmacokinetic (PK) and pharmacodynamic (PD) parameters for illness management. These techniques aid in the provision of multiscale representations of biological processes, beginning with proteins and genes and progressing through cells, isolated tissues and organs, and the whole organism.

    Abstract Main conclusion: The review summarizes our advanced understanding of the heterotrimeric G-protein research from model plants and their emerging roles in modulating various plant architecture and agronomical traits in crop species. Heterotrimeric G-proteins (hereafter G-proteins), consisting of G-alpha (Gα), G-beta (Gβ) and G-gamma (Gγ) subunits, are key signal transducers conserved across different forms of life. The discovery of plant lineage-specific G-protein components (extra-large G-proteins and type-C Gγ subunits), inherent polyploidy in angiosperms, and unique modes of G-protein cycle regulation in plants pointed out to a few fundamental differences of plant G-protein signaling from its animal counterpart. Over the last 2 decades, extensive studies in the model plant Arabidopsis thaliana have confirmed the involvement of G-proteins in a wide range of plant growth and development, and stress adaptation processes. The G-protein research in crop species, however, is still in its infancy, and a handful of studies suggest important roles of G-proteins in regulating plant architectural and key agronomical traits including plant's response to abiotic and biotic factors. We propose that the advancement made in plant G-proteins research will facilitate the development of novel approaches to manage plant yield and fitness in changing environments.

    Abstract Background: The Health Planning Process under National Health Mission (NHM) is participatory in nature and the State Programme Implementation Plan (PIP) is an aggregation of District PIPs which is examined and approved by the National Programme Coordination Committee (NPCC), Ministry of Health and Family Welfare, Government of India. Many times there are delays in releasing of Record of Proceedings (ROPs)/approvals. This affects utilisation of NHM funds at district level and below and desired outcomes are not achieved. The present study aims to analyse the process of fund flow, disbursement and utilisation of funds on various components under Reproductive Maternal New born Child and Adolescent Health (RMNCH+A) in the district Gurugram.
    Methodology: The study was conducted in the District Gurugram of Haryana State, India. One Community Health Centres (CHCs), two Primary Health Centres (PHCs) and four Sub Health Centres were randomly selected. Primary and secondary data were collected in the study. Medical Officer (I/C), Accounts Staff and Health Workers were interviewed using separate schedules regarding process of disbursement, delays in release and utilisation of funds. Separate checklists were prepared to collect data on availability and utilisation of funds at District, CHC and PHC levels under different components of programme.
    Findings: Study found that PIP is prepared with inputs from Block level but community participation at (PHC) and below was not present. There was a delay in reaching funds to district due to delayed release of ROPs. Almost 30%-40% of the budget could not be utilised due to delay in receiving of budget. Utilisation of funds was less in some programme activities due to vacant positions project staff. Only 38% and 31% of the funds were utilised under the child health and family planning budget head for the district of Gurugram in the year 2016-17. Accounts staffs were overburdened which affected monitoring of funds utilisation. Budget release from State to District and below was through e-Banking. Auxiliary Nurse Midwives (ANMs) at Sub centre used to get Untied Funds at the end of third quarter. The Government introduced new 18 broad budget heads in NHM Budget for improving utilisation of budget.
    Conclusion: Delayed release of ROPs and erroneous estimation of budget under the programme, very rigid and large number of budget heads poses challenges of understanding and analysing expenditure and affects utilisation of funds under the NHM. Moreover, vacant positions in the programme, unrealistic planning, weak community participation in planning of expenditure and unexplained budget cut in ROPs were main challenges faced by the District.
