Antibacterial Photodynamic Therapy by Zn(II)-Curcumin Complex: Synthesis, Characterization, DFT Calculation, Antibacterial Activity, and Molecular Docking.

The increase in antibacterial drug resistance is threatening global health conditions. Recently, antibacterial photodynamic therapy (aPDT) has emerged as an effective antibacterial treatment with high cure gain. In this work, three Zn(II) complexes viz., [Zn(en)(acac)Cl] (1), [Zn(bpy)(acac)Cl] (2), [Zn(en)(cur)Cl] (3), where en=ethylenediamine (1 and 3), bpy=2,2'-bipyridine (2), acac=acetylacetonate (1 and 2), cur=curcumin monoanionic (3) were developed as aPDT agents. Complexes 1-3 were synthesized and fully characterized using NMR, HRMS, FTIR, UV-Vis. and fluorescence spectroscopy. The HOMO-LUMO energy gap (Eg), and adiabatic splittings (ΔS1-T1 and ΔS0-T1 ) obtained from DFT calculation indicated the photosensivity of the complexes. These complexes have not shown any potent antibacterial activity under dark conditions but the antibacterial activity of these complexes was significantly enhanced upon light exposure (MIC value up to 0.025 µg/mL) due to their light-mediated 1 O2 generation abilities. The molecular docking study suggested that complexes 1-3 interact efficiently with DNA gyrase B (PDB ID: 4uro). Importantly, 1-3 did not show any toxicity toward normal HEK-293 cells. Overall, in this work, we have demonstrated the promising potential of Zn(II) complexes as effective antibacterial agents under the influence of visible light.

Exploring the potential of Diplosphaera mucosa VSPA for the treatment of petroleum effluent with simultaneous lipid production.

The discovery of unexplored, robust microalgal strains will assist in treating highly polluted industrial effluent, including petroleum effluent. In the current analysis, a newly isolated microalgal strain, Diplosphaera mucosa VSPA, was used to treat petroleum effluent in a lab-scale raceway bioreactor. Its treatment efficiency was compared with a well-known species, Chlorella pyrenoidosa. The D. mucosa VSPA strain proliferated in petroleum effluent at a high growth rate, with final biomass, and lipid concentrations reaching 6.93 g/L and 2.72 g/L, respectively. Treatment efficiency was calculated based on the final removal efficiency of ammonium nitrogen, phosphate phosphorus, and chemical oxygen demand, which was more than 90%. Control experiments suggested that the maximum removal of pollutants from petroleum effluent was due to microalgae growth. Some growth models, including the Gompertz, Logistic, Stannard, Richard, and Schnute, were used to simulate the experimental data, verifying the results. Good fitting of all models was obtained, with the R2 value reaching more than 0.90. The development of a suitable model can help in decreasing the efforts required for the scale-up of the process.

Relational Empathy, Holistic Care, and Quality of Life in Persons With Spinal Cord Injuries: A Cross-sectional Study.

INTRODUCTION: High-quality health systems are built on the concept of patient-centered approach, which includes holistic care and empathy. With time, this has progressively been recognized as a valuable paradigm for better health outcomes, particularly in chronic diseases. OBJECTIVES: The study aims to determine the patients' perception during their consultation and to assess the relationship between Consultation and Relational Empathy measure with demographic/injury variables and quality of life. METHODS: The present cross-sectional study was conducted among 226 individuals with spinal cord injuries. Data were collected via structured questionnaire, World Health Organization-Quality of life BREF, and Consultation and Relational Empathy measure. Independent t test is used to compare World Health Organization-Quality of life BREF domains with two groups of Consultation and Relational Empathy measure. Logistic regression was used to determine the significant factors of Consultation and Relational Empathy measure. RESULTS: In the logistic regression analysis, it was observed that higher quality of life score has significantly higher odds of getting higher Consultation and Relational Empathy score with a remarkable odds ratio (odds ratio = 1.0264, 95% confidence interval = 1.0121-1.0261, P = 0.0001, 0.0472, 0.0001). CONCLUSIONS: The quality of life of the present population is closely associated with greater perceptions of holistic care and empathy in the therapeutic patient-provider relationship. Lack of coordination, poor quality of life, and limited communication between patient and provider may arise when the latter focuses only on treating disease rather than treating a patient as a "whole person."

Home-based intensive nutrition therapy improves frailty and sarcopenia in patients with decompensated cirrhosis: A randomized clinical trial.

BACKGROUND AND AIM: The majority of patients with decompensated cirrhosis suffer from malnutrition, a potentially modifiable contributor to frailty and sarcopenia. The present study investigated the impact of a 6-month dietician-supported home-based intensive nutrition therapy (HINT) intervention on objective frailty and sarcopenia metrics in patients with decompensated cirrhosis. METHODS: One hundred adult patients with decompensated cirrhosis, frailty, and sarcopenia at baseline were randomized 1:1 to receive standard medical therapy (SMT) plus HINT (intervention) versus SMT (control) alone. The primary outcome was an improvement in frailty as measured by the liver frailty index (LFI). Secondary outcome measures included sarcopenia metrics, liver disease severity scores, hospitalization, and death. RESULTS: The LFI improved more in the intervention arm as compared with controls (0.8 vs 0.4; P < 0.001). Baseline and end-of-study skeletal muscle index (SMI) was available in a subset of 32 male patients, with greater improvements seen in the intervention arm compared with controls (6.36 vs 0.80; P = 0.02). Patients in the intervention arm had less hospitalizations over the 6-month follow-up (19 [38%] vs 29 [58%]; P = 0.04). On subgroup analysis, in the 64% of patients who were adherent to calorie and protein intake targets at 6 months, significant improvement was seen in liver disease severity scores and survival (P < 0.05). CONCLUSION: In patients with decompensated cirrhosis, frailty, and sarcopenia, a 6-month dietitian-supported home-based intensive outpatient nutrition therapy was associated with statistically and clinically relevant improvement in frailty. The subgroup of adherent patients showed improvement in their liver disease scores and reduction in mortality. These findings support the key role of food as medicine in the management of cirrhosis.

Relapse during opioid use disorder treatment: A pilot study to understand the reasons for opioid use during treatment.

Background: Opioid use is a cause of concern in many parts of the world. About 2.1% Indians use opioids. Opioids are also the most common drugs used by injection drug users in India. Despite various treatment strategies used to manage opioid use disorders (OUDs), relapse is common. A good treatment program would make efforts to address lapses and prevent relapse. Hence, there is a need to understand the factors associated with relapse in OUD. Method: One hundred and twenty patients completed a baseline assessment that included socio-demographic details and the Maudsley Addiction Profile (MAP). They were followed up for three months and assessed using telephonic interview for opioid use. All those who relapsed were assessed using the Reasons for Relapse Questionnaire (RRQ). The patients who relapsed were compared with the patients who were abstinent. Relapse was defined as any use of opioid during follow-up. Results: Forty participants relapsed during the 90 days of the study period. Relapsed patients had a greater number of conflict days with family members, used a higher amount of heroin and cannabis at baseline, were less likely to be discharged on buprenorphine, and were more likely to drop out. Participants cited mood and social reasons more often than cue/craving and unwell domains of RRQ. Conclusion: Baseline treatment and prospective factors are associated with relapse in OUD. Addressing these factors can help in reducing relapse in OUD patients.

Multiple cycles of granulocyte colony-stimulating factor in decompensated cirrhosis: a double-blind RCT.

BACKGROUND: Liver transplant, the definitive treatment of decompensated cirrhosis (DC), is constrained by donor shortage and long-term complications. Granulocyte colony-stimulating factor (G-CSF) has been explored as an alternative option in open-label studies. This double-blind, randomized, placebo-controlled trial was designed to elucidate the efficacy of G-CSF in DC. METHODS: Seventy patients were randomized to either G-CSF plus standard medical therapy (group A, n = 35) or placebo plus standard medical therapy (group B, n = 35). Primary outcome was 12-month overall survival in patients who received at least one cycle of intervention. Secondary outcomes were mobilization of CD34+ cells at day 6, improvement in Child-Turcotte-Pugh (CTP), and model for end-stage liver disease (MELD), liver stiffness measurement, quality of life, nutrition, hepatic decompensation, infection, hospitalization, and acute kidney injury. RESULTS: Survival in group A was higher than that in Group B although the difference was not statistically significant (87.9% vs 66.7%; p = 0.053). CD34+ cells at day 6 were significantly higher in group A as compared to baseline (p < 0.001). Ascites control (p = 0.03) and CTP score improvement (p = 0.02) were better in group A at 12-months. Encephalopathy episodes (p = 0.005), infections (p = 0.005) were fewer in group A than group B at 12 months. Other secondary outcomes did not improve post-therapy. There were no treatment-related discontinuations or severe adverse events. CONCLUSIONS: G-CSF therapy is safe. The improvement in survival at 12 months is not statistically significant. Better control of ascites, improvement of CTP score, fewer encephalopathy episodes and decreased rate of infections were observed with G-CSF therapy (NCT03911037). Trials Registration NCT03911037.

Are Low Serum Vitamin D Levels a Risk Factor for Advent of COVID-19 Associated Rhinocerebral Mucormycosis: A Preliminary Case Control Study.

To determine whether low serum vitamin D level is a risk factor for development of Rhinocerebral mucormycosis in COVID-19 afflicted patients. A case control study was conducted in a tertiary care hospital utilizing the archived records of COVID-19 afflicted Rhinocerebral mucormycosis cases and age and gender matched controls. The mean value (± standard deviation) of vitamin D level in patients with Mucormycosis was 19.65 ± 13.07 ng/ml and in control subjects it was 27.88 ± 18.04 ng/ml.There was a significant difference between groups (p = 0.02). Thus, low Vitamin D level may be implicated as a risk factor for the advent of mucormycosis in a COVID-19 afflicted patient and therefore Vitamin D supplements may be provided to such patients to achieve normal serum levels.

Combination of Resveratrol and Quercetin Causes Cell Growth Inhibition, DNA Damage, Cell Cycle Arrest, and Apoptosis in Oral Cancer Cells.

Resveratrol and quercetin alone are well reported to have anticancer potential, but their combination studies are very inadequate. We have examined their combination in Cal-33 and SCC-15 oral cancer cells (OCCs) and noncancerous HEK-293 cells. Combination of 10 µM concentration of each resveratrol and quercetin brought additive effect on cellular growth, DNA damage, S-phase cell cycle arrest, and cell death in Cal-33 cells but not in the HEK-293 cells. Augmentation of the cell cycle regulatory protein, Cyclin E, and downregulation of Cyclin A possibly caused S-phase arrest in Cal-33 cancer cells. Comet formation and presence of gamma-H2AX foci confirmed DNA damage, and cleavage of PARP1 and upregulation in Bax level specified apoptosis after combined treatment. Ratio of transcription activation and repression histone marks was found increased after alone as well as combined treatment. Histone deacetylase (HDAC)1, HDAC3, and HDAC8 were downregulated by resveratrol alone and combined treatment. Conclusively, combination of resveratrol and quercetin brings cell growth inhibition, DNA damage, and cell cycle arrest in OCCs but not in normal cells. Additionally, combined treatment causes downregulation of HDACs and apoptosis in cancer cells and it could be an incisive strategy against oral cancer.

Photobiomodulation Alleviates Postoperative Discomfort After Mandibular Third Molar Surgery.

PURPOSE: Surgical removal of mandibular third molars is associated with some degree of postoperative pain, trismus, and facial swelling. The purpose of the study was to evaluate the effect of photobiomodulation in reducing these postoperative side effects after surgical removal of mandibular third molars. MATERIALS AND METHODS: This randomized, double-blinded, split-mouth pilot study was carried out in the Department of Oral and Maxillofacial Surgery, Post Graduate Institute of Dental Sciences, Rohtak, India, among patients with impacted mandibular third molars. In each patient, 1 side was treated by photobiomodulation and the other side received placebo. Photobiomodulation was performed by intraoral and extraoral application of an 830-nm and 30-mW laser at different time points. Pain, trismus, and facial swelling were evaluated at all time points. The number of analgesics taken also was recorded. The data were analyzed using descriptive, bivariate and multivariate statistics. RESULTS: The study was conducted in 25 patients (56% male patients) with a mean age of 22.16 ± 4.60 years. There were 50 sites divided equally into both groups. The sites treated with photobiomodulation showed a significant reduction in pain and swelling (P < .05) compared with the sites in the placebo group. Moreover, an increase in mouth opening was noted after photobiomodulation compared with that in the placebo group, but this was not statistically significant (P > .05). CONCLUSIONS: The results of this study suggest that photobiomodulation is effective in reducing pain and swelling after mandibular third molar surgery. Hence, it can be used as an alternative and effective modality after surgical removal of mandibular third molars, thereby improving the quality of life of the patients.

Dexmedetomidine as an Additive to Local Anesthesia: A Step to Development in Dentistry.

PURPOSE: The study aimed to compare the effect of dexmedetomidine added to lidocaine against epinephrine added to lidocaine on local anesthetic potency and to look for future prospects of dexmedetomidine as an additive to local anesthesia in dentistry. MATERIALS AND METHODS: The study included 25 healthy volunteers in whom extraction of all first premolars was scheduled as part of their orthodontic treatment plan. In this split-mouth, double-blind, crossover, randomized controlled trial, patients were randomized into 2 groups: Group 1 received injection lidocaine plus dexmedetomidine, and group 2 was administered lidocaine plus epinephrine. Patients were assessed for the onset of action of anesthesia, duration of analgesia, pain perception, and vital signs. RESULTS: The mean values (±standard deviations) for the onset of anesthetic action in groups 1 and 2 were 113 ± 24.9 and 141 ± 34.8 seconds, respectively, for the mandible. For the maxilla, the mean values were 113 ± 24.9 seconds for group 1 and 165 ± 43.8 seconds for group 2. The duration of anesthesia was longer in group 1 (lidocaine plus dexmedetomidine), in which the requirement for the first analgesic on request was seen after a longer time interval, when compared with group 2 (lidocaine plus epinephrine). Pain perception elicited statistically significant results with less perception of pain in group 1 (lidocaine plus dexmedetomidine). The vital parameters remained stable, and the results were not statistically significant. CONCLUSIONS: In this study, we observed that the addition of dexmedetomidine to lidocaine for maxillary and mandibular nerve blocks significantly prolonged the block duration and shortened the onset of action, as well as improved postoperative analgesia in terms of the need for fewer analgesics in the postoperative period. Furthermore, the vital parameters remained stable and no complications were encountered. The findings were supportive of the use of dexmedetomidine as an adjunct to local anesthetics in dental procedures.

A Comparative Study of Trigger Point Therapy with Local Anaesthetic (0.5 % Bupivacaine) Versus Combined Trigger Point Injection Therapy and Levosulpiride in the Management of Myofascial Pain Syndrome in the Orofacial Region.

AIM: To compare the efficacy of combined local anesthetic injection with 0.5 % bupivacaine and levosulpiride versus local anesthetic injection alone on outcome measures including levels of pain intensity and depression in the management of myofascial pain syndrome in orofacial region. PATIENTS AND METHODS: This was a prospective, randomized, controlled and open-label comparative clinical study. Seventy-four patients diagnosed to have myofascial pain syndrome and fulfilling the inclusion criteria were enrolled for the study. Patients were randomly assigned into 2 groups. Group A received local anesthetic injection (0.5 % bupivacaine) on trigger points and Group B received combined trigger point injection therapy and 50 mg of tablet Levosulpiride orally B.I.D. They were assessed for pain intensity and depression at baseline and at follow-up of 1, 4, 6 and 12 week intervals. RESULTS: The mean age of patients was 44.54 + 15.977 years in group A and 39.97 + 14.107 years in group B (P value = 0.2). Group A comprised of 25 females (67.567 %) and 12 males (32.432 %) while group B had 27 females (75 %) and 9 males (25 %). 70.27 % were diagnosed with moderate depression in group A and 75 % in group B. 18.91 % in group A and 19.44 % in group B were diagnosed with severe depression. When the VAS score and BDI score was compared at the follow-up intervals with the baseline scores in both treatment groups, the mean difference was highly significant at all the follow-up intervals. However when the relative efficacies of two interventions were compared between the two groups, improvement in pain was significant at all the follow-up intervals except the 1st week follow-up whereas the improvement in depression was non-significant at 1st and 4th week interval while it was highly significant at 6th and 12th week intervals. CONCLUSION: The combined therapy with trigger point injection and levosulpiride as antidepressant significantly reduces pain and depression in the study subjects suffering from chronic myofascial pain with moderate to severe depression in the orofacial region.

Cyanoacrylate therapy for the treatment of gastric varices: a new method.

OBJECTIVE: Cyanoacrylate (CYA) injection is recommended for bleeding gastric varices (GV) but with significant adverse effects. Transesophageal endoscopic ultrasound-guided therapy of large GV with a combined coil and CYA injection has shown promising results. However, it is expensive and requires technical expertise. In this study, we aimed to compare the safety and efficacy of a new method with UCYA [undiluated CYA (UCYA) followed by lipiodol-diluated CYA (DCYA)] in the management of large bleeding GV. METHODS: Fifteen consecutive patients with bleeding from large GV (>1 cm) were prospectively treated with DCYA and another 15 patients treated with UCYA retrospectively. All patients in the DCYA group underwent thoracic computed tomography scan to identify glue embolism. RESULTS: Baseline characteristics were similar between the two groups. Rates of GV obliteration and rebleeding were 100% vs 93.3% (P = 0.309) and 6.7% vs 33.3% (P = 0.06) in the DCYA and UCYA groups, respectively. One patient in the UCYA group had needle fixation which led to fatal bleeding after forceful needle extraction. In DCYA group none had glue embolism. CONCLUSIONS: Both UCYA and DCYA are effective in treating bleeding from large GV. DCYA has lower rebleeding rates and tends to have fewer adverse events than UCYA injection, although the differences are not statistically significant. Large-sample-sized prospective randomized trials are required.

Interaction of polyphenol oxidase of Solanum tuberosum with ß-cyclodextrin: Process details and applications.

Polysaccharides differing in structure and chemical nature were screened for their ability to bind non-covalently with polyphenol oxidase (PPO) from potato (as a model) and their effect on enzyme activity. All the polysaccharides selected inhibited the PPO but ß-cyclodextrin showed maximum inhibition under optimum conditions. Process details for the inhibition of PPO were studied with respect to concentration of ß-cyclodextrin, temperature, pH, and time. Higher inhibition constant and lower half life was obtained at 40 °C than at 30 °C in the presence of inhibitor. ß-Cyclodextrin showed mixed type of inhibition of PPO. ß-Cyclodextrin was further exploited as anti-browning agent in selected fruit juices. It not only showed a significant anti-browning effect on freshly prepared potato juice but was also effective in other fruit juices. Better effect was seen in pineapple, apple and pear as compared to banana, sugarcane and guava fruit juices.

In vitro antioxidant profiling of seabuckthorn varieties and their adaptogenic response to high altitude-induced stress.

In the past few years, seabuckthorn plants have gained special attention due to their ability to grow in the harshest of the environment. This adaptability may be contributed by various antioxidants present in the plants besides other morphological adaptation. As in vivo studies cannot be justified without in vitro studies, the present investigation carried out evaluation of both in vitro and in vivo antioxidant potentials of aqueous and alcoholic extracts of the leaves of Hippophae salicifolia (HS) and Hippophae rhamnoides mongolica (HRM) in comparison with Hippophae rhamnoides turkestanica (HRT). The results had clearly depicted that in vitro antioxidant potential of the extracts was responsible for the in vivo adaptogenic performance in animals during cold and hypoxia exposure under restraint stress. Total phenolic content (TPC), total flavonoid content (TFC), total protein content, and antioxidant potential were determined. For adaptogenic studies, rats with oral drug supplementation were exposed to Cold-hypoxia-restraint (C-H-R) stresses-induced hypothermia, as a measure of endurance. Aqueous extracts of HS showed maximum (99 %) resistance compared to HRT (81 %) and HRM (29 %). The levels of biochemical parameters such as malondialdehyde (MDA), reactive oxygen species (ROS), lactate dehydrogenase (LDH), superoxide dismutase (SOD), glutathione (GSH/GSSG), and catalase (CAT) in blood samples also revealed that the aqueous leaf extract of HS has better antioxidant and adaptogenic potential compared to HRM.

A Comparative Pilot Study to Evaluate the Adjunctive Role of Levosulpride with Trigger Point Injection Therapy in the Management of Myofascial Pain Syndrome of Orofacial Region.

PURPOSE: To evaluate the effect of therapy with levosulpride combined with conventional trigger point injection therapy in terms of pain and depression in the chronic myofascial pain syndrome patients. MATERIALS AND METHODS: This was a comparative prospective study in which subjects with at least one trigger point and symptom duration of at least 3 months were recruited and randomized into two groups. Group A subjects received trigger point injections with 0.5 % bupivacaine and tablet levosulpride and group B received trigger point injections and a placebo. Subjects were assessed for pain with visual analog scale (VAS) and depression with Beck's depression inventory (BDI) at the follow-up periods of 1, 4, 6 and 12 weeks. The treatment effect was measured in terms of mean difference of BDI and VAS scores at various studied intervals from the baseline values. RESULTS: The sample was composed of 15 subjects with 8 in group A (6 females and 2 males, with a mean age of 41.88 ± 15.13 years, disease duration of 12.37 ± 16.11 months) and 7 in group B (6 females and 1 male, with a mean age of 43.86 ± 12.34 years, disease duration of 9.64 ± 9.34 months). The mean baseline VAS score and BDI score was 6.75 ± 1.03 in group A and 6.86 ± 1.06 in group B and 24.25 ± 10.20 in group A and 24.43 ± 11.16 in group B respectively. The mean difference of VAS scores at 12th week interval from the baseline values was highly significant. Although the mean difference of VAS scores at all the other intervals and mean difference of BDI scores at all the intervals was statistically nonsignificant, there was improvement in the mean differences at all the follow-up intervals in terms of both pain as well as depression. CONCLUSIONS: The combined therapy with conventional trigger point injection and levosulpride as antidepressant significantly reduce pain and depression in the study subjects suffering from chronic myofascial pain with moderate to severe depression in the orofacial region.

Anticancer activity of the roots of Ichnocarpus frutescens R. Br. and isolated triterpenes.

The roots of Ichnocarpus frutescens along with roots of Cissampelos pareira, Bauhinia vahlii and Ardisia solanacea are processed together and given orally to cure stomach cancer by the tribes of Chotanagpur and Santhal parganas of Bihar, India. In vitro anticancer activity of the residue from methanolic extract of roots of I. frutescens (MIF) and isolated triterpenes were evaluated by 3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay using MCF-7, BEL-7402, SPC-A-1 and SGC-7901 cancer cell lines. MIF showed significant anticancer activity on four cancer cell lines with IC50 values 163.5±3.58, 156.3±2.95, 142.6±2.60 and 112.4±1.85 respectively as compared to vehicle treated control. Ursolic acid showed anticancer activity on four cancer cell lines with IC50 values 8.5±0.29, 9.9±0.12, 8.1±0.40 and 6.2±0.23 respectively, while IC50 values for α-amyrin on four cancer cell lines was found to be 7.2±0.12, 8.2±0.29, 7.6±0.06 and 5.0±0.12 respectively.

Psychiatric morbidity in chronic respiratory disorders in an Indian service using GMHAT/PC.

OBJECTIVE: The study aimed to assess psychiatric morbidity in stable chronic respiratory disorders and to examine the pattern of psychiatric illness in specific respiratory disorders in Northern India. METHODS: All consecutive patients with stable chronic respiratory illnesses who attended the respiratory disease clinic were recruited in the study. Their healthy attendants were interviewed as a control group. The research clinician, trained in the use of the Global Mental Health Assessment Tool, Primary Care Version (GMHAT/PC), interviewed all the participants. The respiratory consultant made the respiratory illness diagnosis. The data were analyzed comparing the patient and the control group by using relative risk and adjusted odds ratios. RESULTS: Of 391 patients with respiratory illness, 44.8% had a mental illness identified by GMHAT/PC interview compared with 24.3% of 177 attendants (controls). Anxiety (20.6%), depression (13.2%) and obsessive compulsive disorders (4.6%) were the most frequently identified mental disorders in the respiratory disease group. Chronic obstructive pulmonary disease and bronchial asthma when combined with rhinitis had a significantly higher prevalence of comorbid mental illness than those illnesses alone. CONCLUSION: Patients with chronic respiratory illness have high mental health comorbidity. Physicians and practitioners can be trained to identify mental illness using computer-assisted tools such as GMHAT/PC (which is easy to use by clinicians and well accepted by patients). A holistic approach of providing care to such patients may improve their overall outcome and quality of life.

Prospective analysis of temporomandibular joint reconstruction in ankylosis with sternoclavicular graft and buccal fat pad lining.

PURPOSE: To evaluate the feasibility of sternoclavicular graft (SCG) as an adaptive center along with buccal fat pad (BFP) lining for temporomandibular joint (TMJ) reconstruction in TMJ ankylosis. PATIENTS AND METHODS: A prospective, preliminary, short-term study with only 6 months' follow-up was performed in 10 patients with TMJ ankylosis. All patients had complete osseous ankylosis, and the mean duration of ankylosis was 6.4 years (range, 3 to 13 years). Interpositional arthroplasty with SCG along with BFP lining was done in all cases. Postoperative clinical and radiographic follow-up was performed for 6 to 9 months. RESULTS: Maximum interincisal opening at 6 months' follow-up was 35.6 ± 4.97 mm (range, 31 to 45 mm). Similarly, protrusive movement at follow-up of 6 months was 2.7 ± 1.25 mm (range, 1.5 to 5.5 mm), whereas laterotrusive movement was 4.1 ± 1.98 mm (range, 1.5 to 7.0 mm) toward the affected side and 2.4 ± 0.99 mm (range, 1 to 4.0 mm) toward the normal side. After 3 months, 9 of 10 patients had no pain on function, and all the patients were relieved of pain at the end of 6 months. On radiographic follow-up at 9 months, there was noticeably significant adaptation and remodeling of SCG as observed on panoramic radiography and computed tomography scan. In all the patients there was some degree of mandibular deviation toward the operated side, although the occlusion was satisfactory and they were pleased with the outcome. CONCLUSION: On the basis of the findings of this study, we conclude that after release of TMJ ankylosis, reconstruction with SCG combined with interposition of BFP lining followed by vigorous physiotherapy is a successful strategy for the management of TMJ ankylosis with short-term follow-up of 6 months.

A study on the method of Taila Bindu Pariksha (oil drop test).

Taila Bindu Pariksha, an ancient method of urine examination for ascertaining the prognosis of diseases, was very popular in the medieval period, the use of which became obsolete after 17(th) Century AD. Technique of this test is very crude and there are chances of variations in the observations. To revive this technique, it is necessary that the methodology of this test should be standardized so that the observations could be reproducible. To standardize the technique, apparently healthy volunteers were selected and various parameters were standardized for doing this test, i.e., shape and size of Patra (testing containers), volume of the urine, size of the oil drop, height of the oil drop from the surface of urine, variety of sesame oil, etc., Based on the literature, the parameters were changed one by one and observations were noted down. The whole method was recorded in the form of video clips for proper evaluation. The parameters standardized on the basis of observations can be considered as standard to be referred in future studies.

Seabuckthorn attenuates cardiac dysfunction and oxidative stress in isoproterenol-induced cardiotoxicity in rats.

We investigated the effects of seabuckthorn (SBT) oil in isoproterenol (ISO)-induced cardiotoxicity with reference to hemodynamic, antioxidant, histopathological, and ultrastructural parameters. Rats were administered SBT oil (5, 10, and 20 mL/kg per d) or vehicle orally for 30 days along with ISO (85 mg/kg, subcutaneously, at 24-hour interval) on 29th and 30th day. On 31st day, ISO control rats showed cardiac dysfunction, increased lipid peroxidation, depletion of cardiac injury marker enzymes, and antioxidant activities. Myocardial necrosis, edema, and inflammation were evident from the light microscopic and ultrastructural changes. Seabuckthorn oil at the dose of 20 mL/kg per d significantly modulates hemodynamic and antioxidant derangements. The preventive role of SBT oil on ISO-induced cardiotoxicity was reconfirmed by histopathological and ultrastructural examinations. Thus, the present study reveals that SBT oil mitigates myocardial damage in ISO-induced cardiac injury in rats by maintaining hemodynamic, biochemical, histopathological, and ultrastructural perturbations owing to its free radical scavenging and antioxidant activities.
