Effect of long-term medium to high-dose inhaled budesonide on bone mineral density in children with asthma: a cross-sectional study.

OBJECTIVE: The objective of this study was to examine the impact of long-term medium to high-dose inhaled budesonide on bone mineral density in children with asthma. METHODS: We conducted a cross-sectional study in children aged 7-17 years with asthma, who received long-term (≥2 years), medium to high-dose inhaled budesonide (≥400µg/day in 6-11 years old; ≥800 µg/day in >11 years old). We measured bone mineral density (BMD) using dual-energy X-ray absorptiometry and compared it with reference Indian normative values. RESULTS: Thirty-five children with moderate to severe asthma receiving long-term medium to high-dose inhaled budesonide, were included in the study. We found a significantly low lumbar-spine BMD in the study population compared to reference Indian values (p-value 0.002). Eight cases had short stature. Despite the adjustment for height-age in these short-stature cases, lumbar-spine BMD remained significantly low in the study population (p-value 0.020). No significant difference was found in 25-hydroxy vitamin D levels between subjects with "low BMD" and "BMD z-score > -2". CONCLUSIONS: The findings of this study suggest that long-term medium to high-dose inhaled budesonide treatment in children with asthma is associated with decreased BMD. However, further investigation with a larger sample size is necessary to confirm this relationship.

Neuroprotective Potential of Hydroalcoholic Extract of Centella asiatica Against 3-Nitropropionic Acid-Induced Huntington's Like Symptoms in Adult Zebrafish.

Huntington's disease (HD) is an inherited neurodegenerative disease. 3-Nitropropionic acid (3-NP) causes increased reactive oxygen species production and neuroinflammation. Centella asiatica (CA) is a strong antioxidant. The aim of this study is to investigate the effect of hydroalcoholic extract of C. asiatica (HA-CA) on 3-NP-induced HD in adult zebrafish. Adult zebrafish (∼5-6 months old) weighing 470 to 530 mg was used and treated with 3-NP (5 mg/kg intraperitoneal [i.p.]). The animals received HA-CA (80 and 100 mg/L) daily for up to 28 days in water. Tetrabenazine (3 mg/kg i.p.) was used as a standard drug. We have done an open field test (for locomotor activity), a novel tank diving test (for anxiety), and a light and dark tank test (for memory), followed by biochemical analysis (acetyl-cholinesterase [AchEs], nitrite, lipid peroxidation [LPO], and glutathione [GSH]) and histopathology to further confirm memory dysfunctions. 3-NP-treated zebrafish exhibit reductions in body weight, progressive neuronal damage, cognition, and locomotor activity. The HA-CA group significantly reduced the 3-NP-induced increase in LPO, AchEs, and nitrite levels while decreasing GSH levels. Oral administration of HA-CA (80 or 100 mg/L) significantly reduces 3-NP-induced changes in body weight and behaviors, in addition to neuroinflammation in the brain by lowering tumor necrosis factor-α and interleukin-1ß levels. Moreover, HA-CA significantly decreases the 3-NP-induced neuronal damage in the brain. HA-CA ameliorates neurotoxicity and neurobehavioral deficits in 3-NP-induced HD-like symptoms in adult zebrafish.

Drug-herb combination therapy in cancer management.

Cancer is the second leading cause of fatality all over the world. Various unwanted side effects are being reported with the use of conventional chemotherapy. The plant derived bioactive compounds are the prominent alternative medicinal approach for reduction of chemotherapy associated side effects. The data is collected from Pubmed, Sci-hub, Google scholar, and Research gate were systematically searched up to year 2020. Several herbal drugs have been investigated and found with grateful anti-cancer potentials hence, it can be used in combination with chemotherapy for the depletion of associated side-effects. Herbal drugs and their extracts contain a mixture of active ingredients, which show interactions within themselves and along with chemotherapeutic agents to show either synergistic or antagonistic therapeutic effects. Therefore, it is necessary to develop alternative treatment to control chemotherapy associated side-effects. In this review, we discussed some of the significant chemical compounds, which could be efficient against cancer. This review focuses on the different herbal drugs that play an important role in the treatment of cancer and its associated side-effects. This study aimed to evaluate the efficacy of herbal treatment in combination with chemotherapy for cancer treatment.

Need for Testing and Supplementation of Vitamin D3 After Release of COVID-19 Lockdown in Patients with Increased Musculoskeletal Pain.

AIMS: To evaluate vitamin D3 levels in patients who presented with increased musculo-skeletal pain after release of lockdown period when compared to pre-lockdown status. INTRODUCTION: During this COVID pandemic, many countries have implemented lockdown measures and people have to work from home and many students and workers have to restrict themselves to home. During this period, their outdoor activities were limited. After the partial release of this lockdown many of them started to have some kind of physical activity and started experiencing body pains. We evaluated such patients for vitamin D3 levels and symptoms of fibromyalgia. METHODS: This is a retrospective analysis of patients from age group 18-60 presented to outpatient department or on telephonic consultation after partial release of lockdown. All patients who had mild back ache before lockdown and had symptoms exaggerated during this lockdown release were included. All patients were investigated for vitamin D3, PTH, thyroid profile, liver functional and kidney functional tests. RESULTS: Out of 120 patients presented to us in a period of 3 months, 31 patients had increased symptoms when compared to pre-lockdown status. 20 out of 31 patients had low vitamin D3 levels. 14 patients also developed symptoms of fibromyalgia. CONCLUSION: There might be many reasons for increased pain during lockdown, but we focussed specially only on vitamin D3 because of its association with increased symptoms of COVID-19. This is a gentle reminder to test for vitamin D3 levels and supplement if found deficient.

Pharmacodynamic appraisal of wound-healing herbs of Sushruta Samhita.

Background: In Sushruta Samhita, various medicinal plants as single and compound formulations having Vrana-Shodhana (wound cleansing) and Vrana-Ropana (wound healing) potential are enumerated. There are no published data available on these wound-healing medicinal plants of Sushruta Samhita. The effectivee management of wound is necessary in the immunocompromised and chronic wounds patients as they take more time to heal. Aim: To review and systematically analyze wound-healing medicinal plants and their modus-operandi on the basis of pharmacodynamics attributes, i.e., Rasa (taste), Veerya (potency), and Vipaka (biotransformation) in the various stages of healing. Materials and methods: Review of Sushruta Samhita was done to gather wound-healing medicinal plants; pharmacodynamics attributes were gatherd from various Nighantus to understand their role in wound healing. The contemporary information about wound-healing mechanism was gathered from PubMed to interpitate the rational use of plants in the various stages of wound healing. Results: The study suggests that 43 medicinal plants have Vrana-Shodhana activity, 48 have Vrana-Ropana and 62 have both Vrana-Shodhana and Vrana-Ropana potential. Medicinal plants with Vrana-Shodhana category are having predominance of Katu (pungent), Tikta (bitter) and Kashaya (astriengent) Rasa. Plants under Vrana-Ropana are having Madhura, Kashaya Rasa (sweet taste), Madhura Vipaka (sweet biotransform) and Sheeta Veerya (cold potency). Conclusion: Plants having Tikta, Kashaya Rasa, Katu Vipaka, and Sheeta Veerya may be useful in the inflammatory stage, plants having Madhura, Kashaya Rasa and Sheeta Veerya may be useful in the prolifiratory stage and plants having Madhura Rasa, Sheeta Veerya, and Madhura Vipaka may be useful in the remodeling stage. The present review will help to give the directions to the researchers for the development of effective wound-healing medicines for wounds.

Mycobacterium tuberculosis Infection of the Spine Secondary to Oxygen - Ozone Therapy for Prolapse Intervertebral Disc: A Scoping Review.

Introduction: Ozone therapy is one of the evolving, yet far from conclusive, alternative minimally invasive treatment option in the management of herniated disc in the cervical and lumbar spine. It causes the decrease in the volume of herniated disc by dehydration. Case Report: We hereby present the first reported case of Mycobacterium infection of the spine secondary to ozone therapy with the aim to caution the surgeons regarding the complications of intradiscal ozone therapy. Conclusion: Lack of proper, adequate, and recommended precautions if not taken can inoculate the varied microorganisms into the intradiscal space leading to devastating and unforeseen complications.

Vitamin D Supplementation in Patients with Chronic Low Back Pain: An Open Label, Single Arm Clinical Trial.

BACKGROUND: Vitamin-D deficiency may possibly be related to chronic low back pain (CLBP). OBJECTIVE: The study is aimed to assess the impact of vitamin-D supplementation on pain intensity, functional disability, and vitamin-D levels in patients with CLBP. STUDY DESIGN: Single arm open-label study. SETTING: Outpatient pain clinic of a tertiary care hospital. METHODS: Sixty-eight eligible patients (CLBP for = 3 months, pain score = 50 on visual analogue scale (VAS) and plasma 25-Hydroxyvitamin D3 levels < 30 ng/mL) were enrolled. Patients were supplemented with 60,000 IU of oral vitamin-D3 given every week for 8 weeks. Efficacy parameters included pain intensity and functional disability measured by VAS and modified Oswestry disability questionnaire (MODQ) scores at baseline, 2, 3, and 6 months post-supplementation. Plasma 25(OH) D3 levels were measured at baseline and 8 weeks. RESULTS: Baseline mean (SD) vitamin-D levels were 12.8 (5.73) ng/mL and increased to 36.07 (12.51) post supplementation (P < 0.01). Forty-five (66%) patients attained normal levels (> 29 ng/mL) post supplementation. Significant reduction in VAS was observed at 2, 3, and 6 months [61 (19), 45 (19), 36 (18)] as compared to 81 (19) at baseline (P = 0.001 at all-time intervals). A significant improvement in the functional ability was also observed at 2, 3, and 6 months [36 (12), 31 (13), and 26 (10)] as compared to baseline 45 (16) (P = 0.001 at all-time intervals). CONCLUSION: Vitamin-D supplementation in deficient CLBP patients may lead to improvement in pain intensity and functional ability apart from normalization of the levels. Future controlled clinical trials are required to confirm the hypothesis.Key words: Vitamin D, deficiency, screening, low back pain, chronic, supplementation.

Chemical composition and larvicidal activity of Zanthoxylum armatum against diamondback moth, Plutella xylostella.

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) is the most serious pest of cruciferous crops grown in the world causing economic yield loss. Several synthetic insecticides have been used against P. xylostella but satisfactory control was not achieved due to development of resistance to insecticides. Therefore, the present study was carried out to screen different fractions of Zanthoxylum armatum for their insecticidal activities against second instar larvae of P. xylostella. Results indicate, all the fractions showed activity to P. xylostella. However, n-hexane fraction of Z. armatum showed maximum larvicidal activity with minimum LC50 value of 2988.6 ppm followed by ethanol (LC50 = 12779.7 ppm) and methanol fraction (LC50 = 12908.8 ppm) whereas chloroform fraction was least toxic (LC50 = 16750.6 ppm). The GC-MS analysis of n-hexane fraction of leaf extract showed maximum larvicidal activity, which may be due to two major compounds i.e. 2-undecanone (19.75%) and 2-tridecanone (11.76%).

A new geranylbenzofuranone from Zanthoxylum armatum.

A new geranylbenzofuranone, zantholide (1), and eight known compounds, dodeca-2E,4E-dienoic acid isobutylamide (2), dodeca-2E,4E,8Z,11-tetraenoic acid isobutyl amide (3), zanthoxylin (4), sesamin (5), kobusin (6), asarinin (7), fargesin (8) and armatamide (9), have been isolated from the bark of Zanthoxylum armatum. The structures of the isolated compounds were determined on the basis of spectroscopic (1D, 2D NMR) and HR-ESI-MS data. This is the first report on the isolation of 2 and 3 from the Rutaceae family and 4 from Z. armatum.

Metal-free transfer hydrogenation of nitroarenes in water with vasicine: revelation of organocatalytic facet of an abundant alkaloid.

Vasicine, an abundantly available quinazoline alkaloid from the leaves of Adhatoda vasica, has been successfully employed for metal- and base-free reduction of nitroarenes to the corresponding anilines in water. The method is chemoselective and tolerates a wide range of reducible functional groups, such as ketones, nitriles, esters, halogens, and heterocyclic rings. Dinitroarenes reduced selectively to the corresponding nitroanilines under the present reaction conditions.

Quantitative and structural analysis of amides and lignans in Zanthoxylum armatum by UPLC-DAD-ESI-QTOF-MS/MS.

A rapid and simple ultra performance liquid chromatography-diode array detection (UPLC-DAD) method has been developed for the simultaneous quantification of four biologically important furofuran lignans, asarinin, sesamin, fargesin and kobusin, and an amide, armatamide in Zanthoxylum armatum within 7min. The separation was carried out on a BEH C18 column (2.1mm×100mm, 1.7µm particle size) with 0.05% formic acid aqueous solution and acetonitrile as mobile phase under gradient conditions at 25°C. The method was validated and found to be linear (R(2)≥0.9997), precise in terms of peak areas (intra-day RSDs≤0.62% and inter-day RSDs≤2.95%) and accurate (95.6-104.0%). The developed method was applied to the quality assessment of different parts (leaves, bark and seeds) of Z. armatum including locational variation of leaves samples. Significant variation in the amount of amides and furofuran lignans was observed. Tandem electrospray ionization-mass spectrometry (UPLC-DAD-ESI-MS/MS) of samples led to the identification of sixteen compounds in the category of amides and furofuran lignans.

Identification and cross-species transferability of 112 novel unigene-derived microsatellite markers in tea (Camellia sinensis).

PREMISE OF THE STUDY: Tea Unigene-derived MicroSatellite (TUGMS) markers were identified from the publicly available EST data in Camellia sinensis for characterization and future genome mapping studies in tea. METHODS AND RESULTS: One hundred twelve novel TUGMS markers were identified from 4356 unigenes derived by clustering of 12788 random ESTs in C. sinensis. Amplification-based validation of the TUGMS loci proved them to be highly polymorphic [an average (av.) of 5.24 alleles], heterozygous (H(E), av. 0.746; H(o), av. 0.566) and informative (PIC, av. 0.392). TUGMS loci were 100% transferable in cultivated C. assamica and C. assamica subsp. lasiocalyx and highly cross-transferrable to the related species C. japonica, C. rosiflora, and C. sasanqua. CONCLUSIONS: These 112 novel highly polymorphic TUGMS markers with proven cross-species transferability will facilitate the future genetic diversity and genome mapping studies in tea.

Iron deficiency and infection.

Iron deficiency is the most common micronutrient deficiency in the world. Children, particularly infants living in developing countries are highly vulnerable to infectious diseases. Therefore, understanding the relationship between iron deficiency and infection is of great importance. Iron deficiency is associated with impairment of innate (natural) immunity and cell mediated immunity, thereby contributing to increased risk of infections. The iron acquisition by the microbes and their virulence is determined by various host and microbial mechanisms. Altering these mechanisms might provide modes of future therapy for infectious diseases.

Variability in Neem (Azadirachta indica) with respect to azadirachtin content.

There is a controversy over variations in azadirachtin content in neem (Azadirachta indica) seeds among various provenances and countries. Also, variations in azadirachtins are usually attributed to climatic conditions such as temperature and humidity. The present study was undertaken to evaluate qualitative and quantitative variability in azadirachtins A and B among various neem provenances or individual neem trees. Forty-three provenances of India were examined for intraprovenance variability in azadirachtin A and B content and oil percentage. Twenty-eight individual neem trees from five provenances of different agroclimatic regions were also examined for interprovenance variability. The azadirachtins were quantified using reversed phase analytical HPLC. There were wide variations in oil and azadirachtin contents among different provenances. Azadirachtin A ranged from 556.9 to 3030.8 mg kg(-)(1) of kernels, whereas azadirachtin B was in the range 43.1-590.6 mg kg(-)(1) of kernel among the provenances investigated. Analysis of variance among various neem provenances showed significant differences in oil content, azadirachtin A, total azadirachtin (A + B), and A:B ratio. There were individuals with high and low azadirachtins within a single provenance, and this trend was observed in all of the provenances selected from five agroclimatic regions of the country. Variations among individual trees of a particular provenance indicated that climatic factors such as rainfall, humidity, or temperature did not influence azadirachtin content in the neem trees. The present study shows that there are individual genetic differences among neem trees. A systematic study for tree improvement with a population of mother trees with desired traits should be undertaken by performing half-sib progeny trials and further selections by clonal propagations. The role of genetic makeup needs further research.
