RESUMO

Sustainability is considered to be one of the biggest issues in the current time. This study aims to understand the role of sustainability further by revisiting the much-debated and intricate relationship between economic growth and environmental performance and to provide guidance to policymakers. Using a large sample of data from 180 countries over the period from 2002 to 2017 a measure that captures the various aspects of environmental performance, the study performs a test of the Environmental Kuznets Curve (EKC) hypothesis, which defines the relationship between economic growth and environmental deterioration. Controlling for several associated macroeconomic and governance variables, the results suggest that for certain regions, viz. Asia, Eastern Europe, and North America, higher economic growth, as proxied by per capita GDP, has a negative association with environmental performance (measured by Environmental Performance Indices, EPI), indicating that the former may prove detrimental to the later. The results suggest a unidirectional relationship between the two variables and are also robust to endogeneity concerns that are often emphasized in the EKC literature. The study documents similar results for lower-income and lower-middle-income countries. Interestingly, the authors also find that small-sized governments in developing nations have a positive association with environmental performance.

RESUMO

INTRODUCTION: We aimed to compare the clinical and radiological findings to predict scar integrity in term antenatal mothers with a previous lower segment cesarean section (LSCS). METHODOLOGY: This prospective study was conducted in the obstetrics and gynecology department of LN Medical College, Bhopal, India, from August 2020 to August 2021. We included all pregnant women with term gestation (37+0 to 42+0 weeks) who were admitted either for elective repeat LSCS or for emergency LSCS and had a history of a previous LSCS. A detailed history and clinical examinations were performed. We noted the presence of scar tenderness and conducted transabdominal ultrasound (USG) to assess the integrity of the uterine scar in all women. During surgery, the surgeon identified the lower uterine segment scar and graded it as normal, thinned-out, dehiscent, or ruptured. We calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for both clinical findings (scar tenderness) and ultrasound findings as predictors of scar integrity. RESULTS: A total of 60 pregnant women were included in the study. During a repeat cesarean section, we found a thinned-out scar in 26 women out of 60 (43.3%). Out of 60 women, 13 had scar tenderness, and among these 13 women, 12 had thinned-out scars intraoperatively. Forty-seven women had no scar tenderness; 14 had thinned-out scars intraoperatively. The sensitivity of scar tenderness as a predictor of a thinned-out scar was 46.2%, specificity was 97.1%, PPV was 92.3%, and NPV was 70.2%. Whereas the sensitivity of ultrasound scar thickness as a predictor of a thinned-out scar was only 19.2%, with a specificity of 94.1%, a PPV of 71.4%, and an NPV of 60.4%. Thus, we documented a significant correlation between intraoperative and clinical findings (κ = 0.46; p<0.05), but no agreement could be found between ultrasound and intraoperative findings (p>0.05). CONCLUSIONS: Clinically evident scar tenderness continues to be a useful parameter to predict intraoperative scar status.

RESUMO

INTRODUCTION: One of the primary objectives of orthodontic treatment has been the enhancement of facial aesthetics. To obtain the perfect facial profile with aesthetic balance, knowledge of facial anatomy is essential. The diagnosis and treatment planning of orthodontic patients depend greatly on the examination of the soft tissue profile. Since the nasolabial angle is significantly affected by the inclination of the upper incisors, it is a frequently employed soft tissue parameter in orthodontic diagnosis. AIM: The study aimed to find out the correlation between the nasolabial angles with maxillary incisor inclination. MATERIALS AND METHODS: In this retrospective study, 120 lateral cephalograms of orthodontic patients including males and females were traced. Their nasolabial angle and maxillary incisor inclination were calculated before and after orthodontic treatment. RESULT: The mean of pre- and post-treatment nasolabial angle was found to be 91.43° ± 14.008 and 97.93° ± 14.194, respectively. The mean of pre- and post-treatment incisor inclination was found to be 32.59° ± 7.290 and 23.98° ± 6.851, respectively. The gender-wise Pearson's correlation (r) of nasolabial angle with incisor inclination for male and female was found to be -0.464 with a P value of 0.164 and -0.305 with a P value of 0.118, respectively. Overall Pearson's correlation of nasolabial angle with incisor inclination was found to be -0.040 with a P value of 0.384. CONCLUSION: There is an insignificant negative correlation between nasolabial angle and incisor inclination in the Chhattisgarh population as well as among the two genders.

RESUMO

BACKGROUND: Odontogenic cysts and tumors exhibit different degrees of aggressiveness in their biological behavior. There has been evidence that the presence of myofibroblasts (MFs) at the invasion front promotes tumor invasion. Our study is based on the fact that MFs are important in the biological behavior of odontogenic cysts and tumors. AIM: To assess immunohistochemically expression of alpha-smooth muscle actin (α-SMA) of MFs in odontogenic cysts and tumors and correlate this expression to their biological behavior. MATERIALS AND METHODS: The archival tissues collected for 1.5 years were obtained from the Department of Oral Pathology & Microbiology, People's Dental Academy, Bhopal (India). A total of 40 cases consisting of 10 cases each of odontogenic keratocysts, radicular cysts, dentigerous cysts and ameloblastomas formed the study group. An immunohistochemical analysis of α-SMA expression and localization was carried out. RESULTS: Mean MF counts were the highest in odontogenic keratocysts which was followed by ameloblastomas, entigerous cysts and radicular cysts. Weak α-SMA-expression was found in 50% of cases, moderate in 22.5% of cases, and intense - in 10% cases. MFs were arranged in the spindle, focal, or network patterns in 35; 27.5 and 20% of cases, respectively. CONCLUSION: The analysis revealed that the MFs were distinctly heterogeneous in distribution and pattern of arrangement. This provided persuasive evidence that stroma of these lesions harbor MFs as reflected by α-SMA immunopositive cells.

RESUMO

Background: Coronavirus disease 2019 (COVID-19) was declared as a pandemic by the World Health Organization (WHO) on March 11, 2020. Researchers have evaluated many repurposed drugs for treating COVID-19 in terms of both efficacy and safety in the past several months. It has been seen that vaccination is an effective way to stop the pandemic from spreading further. Being frontline workers dealing with COVID-19 patients, the healthcare workers (HCWs) in public and private sectors were prioritized to get vaccinated first. Also, HCWs are a reliable source of information on vaccination to patients; therefore, their acceptance or otherwise of COVID-19 vaccines may influence the uptake of COVID-19 vaccine among the general population. Methodology: A cross-sectional study was conducted to assess the acceptance and adverse effects following the first dose of COVID-19 vaccine among HCWs of Shaheed Hasan Khan Mewati Government Medical College (SHKM GMC), a tertiary healthcare centre located in the district of Nuh Haryana. Result: In our study, more than half of the respondents (63.8%) experienced mild-moderate anxiety while the rest of the respondents experienced mild anxiety or moderately high levels of anxiety prior to the first dose, which is indicative of hesitancy towards the vaccine. Two-thirds of respondents in our study reported mild and common symptoms following vaccination while the remaining one-third did not report any symptom. More than half of the respondents (67.3%) claimed not taking the first dose even after two months after the initiation of vaccination drive at SHKM GMC, stating fear of some kind of reaction or side-effects, safety concerns regarding vaccine, reservations concerning the success of vaccination, and the efficiency of the vaccine. Conclusion: Our findings highlighted reasons for hesitancy among HCWs regarding COVID-19 vaccination along with the adverse effects encountered after the first dose. COVID-19 vaccine concerns among the HCW population should be addressed so that HCWs can be empowered to lead communication campaigns to improve COVID-19 vaccine uptake among the general population. Thus, it is important to hold such surveys.

RESUMO

Feeling a sense of belonging is a central human motivation that has consequences for mental health and well-being, yet surprisingly little research has examined how belonging shapes mental health among young adults. In three data sets from two universities (exploratory study: N = 157; Confirmatory Study 1: N = 121; Confirmatory Study 2: n = 188 in winter term, n = 172 in spring term), we found that lower levels of daily-assessed feelings of belonging early and across the academic term predicted higher depressive symptoms at the end of the term. Furthermore, these relationships held when models controlled for baseline depressive symptoms, sense of social fit, and other social factors (loneliness and frequency of social interactions). These results highlight the relationship between feelings of belonging and depressive symptoms over and above other social factors. This work underscores the importance of daily-assessed feelings of belonging in predicting subsequent depressive symptoms and has implications for early detection and mental health interventions among young adults.

RESUMO

Recovery and amplification of nucleic acids from archived formalin-fixed tissue samples is the most developing field in retrospective genetic studies. We compared different deparaffinization methods and DNA isolation techniques, and intergroup comparisons were performed to evaluate the effectiveness of different storing methods for archival OSCC samples based on obtained mean DNA quantity, quality, and PCR amplification of the P53 gene. The study comprised 75 archival histologically diagnosed OSCC samples which were divided into Group I: Formalin-fixed paraffin-embedded tissue blocks and Group II: Long-term formalin-fixed tissue. A comparison of different deparaffinization methods showed that xylene deparaffinization is an efficient method to obtain suitable DNA. Comparing different DNA isolation techniques illustrated that the conventional phenol-chloroform method gives better integrity to DNA in contrast with the kit method. Comparison between FFPET and long-term FFT samples demonstrated that samples fixed in formalin overnight and embedded in wax yield better quality and quantity DNA in comparison with long-term samples fixed in formalin. To obtain suitable integrity of DNA, tissue samples should be stored by fixing in formalin overnight followed by preparation of paraffin tissue blocks, deparaffinization by xylene, and subjecting them to the conventional phenol-chloroform DNA isolation protocol.

RESUMO

The correlation of several defects and optical and magnetic properties with Fe content in Zn1-xFexAl2O4 (0.01 ≤ x ≤ 0.40) nanocrystals has been scrutinized through X-ray diffraction, O K-edge X-ray absorption near-edge structure, FT-IR, diffuse reflectance, photoluminescence and electron spin-resonance spectroscopies, and vibrating sample magnetometry. Increasing Fe content causes elongation in the octahedral units of the lattice, accompanied by distortion in the octahedral coordination. Fe introduces non-radiative centres in the forbidden gap, thereby tuning the band gap from 4.37 to 3.88 eV and eliminating emission in the visible region. Zn vacancies are found to tail off, while {\rm Fe}_i^{\bullet \bullet \bullet}, {\rm Al}_{\rm Zn}^\bullet and FeAl× antisite defects increase in concentration with increasing Fe content. Inhomogeneous broadening of spin-resonance signals infers strong spin-lattice interactions of Fe3+ ions at distorted octahedral and non-symmetric tetrahedral sites. A transition is observed from paramagnetism to superparamagnetism at higher Fe concentrations. A visual colour change from pearly white to orange-brown is observed in Zn1-xFexAl2O4 nanocrystals with increasing Fe content, revealing its potential candidature for pigments in the paint and dye industries.

RESUMO

We report, for the first time, the influence of oxygen vacancies on band structure and local electronic structure of [Formula: see text] (SZO) nanophosphors by combined first principle calculations based on density functional theory and full multiple scattering theory, correlated with experimental results obtained from X-ray absorption and photoluminescence spectroscopies. The band structure analysis from density functional theory revealed the formation of new energy states in the forbidden gap due to introduction of oxygen vacancies in the system, thereby causing disruption in intrinsic symmetry and altering bond lengths in SZO system. These defect states are anticipated as origin of observed photoluminescence in SZO nanophosphors. The experimental X-ray absorption near edge structure (XANES) at Zn and Sr K-edges were successfully imitated by simulated XANES obtained after removing oxygen atoms around Zn and Sr cores, which affirmed the presence and signature of oxygen vacancies on near edge structure.

RESUMO

BACKGROUND: Soft tissue vascular malformations are not uncommonly encountered in clinical practice and are often mistaken for other pathologies. Vascular anomalies are divided into vascular tumors and malformations. Vascular malformations progressively increase in size with increasing age and are classified into low-flow (venous, lymphatic, veno-lymphatic, capillary and capillary venous) and high-flow malformations (arteriovenous malformations (AVM) and arteriovenous fistula (AVF)) depending on the presence or absence of arterial flow. AIM: Aim of this study is to evaluate the Magnetic resonance imaging (MRI) features of the soft tissue vascular malformations and to classify the lesions depending on flow pattern. MATERIALS AND METHODS: A total of 52 patients of soft tissue vascular malformations were included in this study over a period of 3 years. All patients underwent detailed clinical examination and dynamic post contrast MRI evaluation. Doppler and ultrasound were done as an adjunct. RESULTS: There were 31 females and 21 male patients with age ranging from 9 to 34 years. In total 33 venous, 11 lymphatic, 8 veno-lymphatic malformations were seen. No case of high-flow malformation was seen. Majority of the lesions involved the head and neck region and the extremities. Fat saturated T2WI, STIR, and 3D dynamic post contrast sequences were found to be the most useful MRI sequences. CONCLUSION: MRI is the modality of choice for evaluating the soft tissue vascular malformations. It depicts the extent of the lesion, classifies the lesions into low or high flow and helps in treatment planning.

RESUMO

In presented work, excitation selective novel cool and cold white emission is reported from dysprosium (Dy) doped SrZnO2nanophosphors, synthesized by combustion technique. The host lattice provided selective excitation routes for Dy3+levels and intrinsic defects levels via charge transfer (270 nm) and host defects absorption bands (375 nm), respectively. The emission due to Dy3+levels was found to be exhibiting cool white emission and that from intrinsic defects was cold white emission, as characterized from correlated color temperature. UV irradiated glow curve analysis complemented the results by exhibiting signal due to Dy assisted traps on near UV exposure (254 nm) and that of host related traps at far UV exposure (365 nm). The luminescence phenomenon is comprehended through proposed band model. The obtained results proclaimed SrZnO2:Dy as a potential member among white emitting phosphors to be used as standard daylight sources in commercial and aesthetic lighting.

RESUMO

PURPOSE: Chronic periodontitis (CP) and Type 2 diabetes mellitus (T2DM) are chronic diseases affecting the humans and have interrelationship in their pathogenesis. Monitoring the progress with biomarker in these disease is important from treatment outcome point of view. We investigated the association of salivary developmental endothelial locus-1 (Del-1) and interleukin-17 (IL-17) levels in CP and T2DM. METHODS: Saliva was collected from 17 healthy and 68 patients (divided into 4 groups based on presence or absence of CP and T2DM). Periodontal parameters were recorded at the time of visit. Del-1 and IL-17 levels in unstimulated salivary samples were determined using enzyme-linked immunosorbent assay. RESULTS: Study found the lower levels of salivary Del-1 and higher levels of IL-17 in CP (2.23 ± 2.10 ng/mL, 56.54 ± 19.79 ng/mL), CCDM ((1.97 ± 1.36 ng/mL, 74.74 ± 17.79 ng/mL) and CUDM (1.02 ± 0.52 ng/mL, 63.84 ± 24.72 ng/mL) as compared to healthy individuals (6.54 ± 2.07; 24.47 ± 8.23 ng/mL) (p < 0.001). Del-1 and IL-17 levels were correlating with inflammatory state in CP and presence of T2DM aggravate the severity of disease in CP. An inverse correlation between salivary Del-1 & IL-17 levels was also seen. Furthermore, we also observed that the combination of T2DM and CP (CCDM and CUDM) increases the salivary IL-17 levels and decreases Del-1 levels. CONCLUSIONS: There is an upregulation of salivary IL-17 and downregulation of salivary Del-1 with increase in severity of periodontal disease as well as T2DM. Furthermore, the presence of T2DM in chronic periodontitis patients can aggravate the inflammation related periodontal destruction.

RESUMO

Complex cation distribution in spinel solid solution, fosters defect generation and permutates the optical properties. To scrutinize the effect on structural properties, viz. the cation distribution and defect states upon substitution of Zn with Mg; and to tune the emission properties, Zn1-xMgxAl2O4 (0.01 ≤ x ≤ 0.30) nanocrystals are synthesized. The nanocrystals show increased inversion and generation of multiple defects, namely zinc vacancies, zinc interstitials, oxygen vacancies and antisite defects with increasing Mg content, which thereby impacts the optical band gap. Pentahedral coordination in addition to tetra- and octahedral coordination of Al has been observed, which infers the presence of oxygen vacancies and dangling bonds. Moire fringes formation has intimated the presence of two or more crystal lattices with higher Mg substitution. Band-to-band and defect-assisted photoluminescence shows the role of multiple defects, especially defect clusters, in deciphering the properties of the resulting crystals. Color change from bluish-white to pink has been achieved depending upon the excitation wavelength and emission mechanism, as proposed through a band model schematic. The presented study may be beneficial for designing the Zn1-xMgxAl2O4 nanocrystals with optimized emission properties.

RESUMO

Remodelling of the actin cytoskeleton in response to external stimuli is obligatory for many cellular processes in the amoebic cell. A rapid and local rearrangement of the actin cytoskeleton is required for the development of the cellular protrusions during phagocytosis, trogocytosis, migration, and invasion. Here, we demonstrated that EhC2B, a C2 domain-containing protein, is an actin modulator. EhC2B was first identified as an effector of EhRab21 from E. histolytica. In vitro interaction studies including GST pull-down, fluorescence-based assay and ITC also corroborated with our observation. In the amoebic trophozoites, EhC2B accumulates at the pseudopods and the tips of phagocytic cups. FRAP based studies confirmed the recruitment and dynamics of EhC2B at the phagocytic cup. Moreover, we have shown the role of EhC2B in erythrophagocytosis. It is well known that calcium-dependent signal transduction is essential for the cytoskeletal dynamics during phagocytosis in the amoebic parasite. Using liposome pelleting assay, we demonstrated that EhC2B preferentially binds to the phosphatidylserine in the presence of calcium. The EhC2B mutants defective in calcium or lipid-binding failed to localise beneath the plasma membrane. The cells overexpressing these mutants have also shown a significant reduction in erythrophagocytosis. The role of EhC2B in erythrophagocytosis and pseudopod formation was also validated by siRNA-based gene knockdown approach. Finally, with the help of in vitro nucleation assay using fluorescence spectroscopy and total internal reflection fluorescence microscopy, we have established that EhC2B is an actin nucleator. Collectively, based on the results from the study, we propose that EhC2B acts like a molecular bridge which promotes membrane deformation via its actin nucleation activity during the progression of the phagocytic cup in a calcium-dependent manner.

RESUMO

Defect states in ZnAl2O4 have a significant role in its applicability as a luminescent material. To understand the nature and distribution of defects in its crystal lattice, thermoluminescence (TL) study has been carried out. Excellent TL response is observed from γ- and ultraviolet-irradiated samples at different doses and exposure durations, respectively. Different type of fuels employed in combustion synthesis show a remarkable effect on the trap distribution and hence luminescence properties. Shallow and deep traps are observed in crystals attributed to O- vacancies and F+ centers. The mechanism of trapping, retrapping and recombination have been depicted through schematic band model diagram. X-ray photoelectron spectroscopy indicated the presence of various types of defects specifically AlZn antisite defect, oxygen and zinc vacancies which are further upheld by photoluminescence and Raman spectroscopy. All results when summed up, predict ZnAl2O4 to be a quality material for dosimetry.

RESUMO

PURPOSE: Temporomandibular joint (TMJ) disc derangement is defined as a malpositioning of the articular disc relative to the condyle and eminence. Arthrocentesis of the TMJ is considered by many as the first-line surgical treatment for patients who do not respond to conservative treatment. The aim of this study is to assist needle insertion for temporomandibular joint arthrocentesis using ultrasonography. MATERIALS AND METHOD: Twenty patients who required arthrocentesis of the TMJ were randomly assigned to two groups A and B undergoing single-puncture arthrocentesis with modified double-lumen single-barrel needle and ultrasound-guided single-puncture arthrocentesis using modified double-lumen single-barrel needle (n = 10 in each group). The number of attempts of needle manipulation, duration of the operative procedural time, and visual analog (VAS) scale score for pain to assess surgical discomfort were the main outcome variables. RESULTS: None of the patients in either group developed any complication with no significant difference in VAS score for pain between the two study groups. The number of attempts for needle manipulation (mean ± SD) for group A was 2.20 ± 0.789, and for group B, it was 1.10 ± 0.316 (p value, 0.0007); operative procedural time (mean ± SD) for group A was 18.5 ± 3.171 min, and for group B, it was 13.1 ± 1.663 (p value, 0.0002) which was significantly lesser in group A than in group B. The sentence signifies that the number of attempts that was required to re-insert the needle to enter the joint space in Ultrasound guided and conventional method of arthrocentesis. CONCLUSION: Ultrasound-guided single-puncture arthrocentesis using a customized needle is a promising method to perform joint lavage with minimal trauma and in a precise manner.

RESUMO

Hereditary ectodermal dysplasia (HED) is a rare genetic disorder chiefly affecting ectodermally derived structures including hair, nails, sweat glands etc. with pathognomic manifestations such as hypotrichosis, hypohidrosis, and hypodontia. Hypohidrotic ectodermal dysplaisa, being the most frequently encountered subtype and HED, being the rare subtype. HED is primarily transmitted through X-linked recessive trait in which the gene is carried by the female and manifested in male. Although rare, this disorder may be seen affecting lot of members of the same family. We hereby report a series of four cases with common classical manifestations accompanied with spoon shaped nails, hyperpigmentation, oligodontia and hypotrichosis. The patients were treated for prosthetic rehabilitation and were asked to wear cool clothing.

RESUMO

Myoepithelial carcinomas are quite infrequent neoplasms and coupled with their diverse morphological appearance are interesting as far as diagnosis and management is concerned. They account for less than 1% of all salivary gland tumors. The variable morphologic appearance of myoepithelial carcinoma leads to a wide differential diagnosis, including primary salivary gland tumors and metastatic tumors. The prognosis of these tumors is not fair as they are locally aggressive and approximately one third of the patients die of the pathology. We report a case of clear cell variant of myoepithelial carcinoma in an unusual location, i.e. the upper lip. The treatment carried out was wide surgical resection. The patient was followed up for 2 years and was symptom free. The clear cell variant of myoepithelial carcinoma is extremely rare and only about 51 cases of this variant affecting the salivary glands have been reported worldwide so far.

RESUMO

Myoepithelial carcinomas (MCs) are difficult to distinguish from their benign counterpart due to diverse morphology. This neoplasm was introduced by Stromeyer et al. in 1975. They comprise of <2% of all salivary gland carcinomas involving most commonly major salivary glands and are characterized by differentiation of tumor cells into myoepithelial cells. The cells may present as epithelioid, plasmacytoid, spindle, clear, stellate and mixed type predominantly. Literature search revealed very few cases reported as clear cell variant of MC. Here, we report a case of clear cell MC involving buccal vestibule extending up to alveolus. The diagnosis was confirmed, and the patient was surgically treated.
