Abstract
AIM The aim of this study was to study the progression of diabetic retinopathy (DR) and macular edema in uncomplicated phacoemulsification in patients with diabetes mellitus with a follow-up of 6 months. METHODS A prospective, nonrandomized study was conducted on patients with established or no DR in a known case of diabetes mellitus undergoing cataract surgery by phacoemulsification, with no intraoperative complications. Detailed ophthalmic evaluation including fundus examination was done in all cases, and DR staging was done. Optical coherence tomography and fundus fluorescein angiography were done in indicated cases. Fundus evaluation was done during the follow-up visits in 3 weeks, 3 months, and 6 months postsurgery and the tests were repeated if necessary. RESULTS In the current study, there was a statistically significant improvement in best-corrected visual acuity after cataract surgery compared to the preoperative value. From the 330 eyes we analyzed, there was a progression of DR in only 18 eyes (5.45%) following phacoemulsification. There was a statistically significant increase in central macular thickness (CMT) at 3 weeks postoperative (433.82 ± 137.572) compared to that of the preoperative CMT (295.98 ± 97.959). From the 22 eyes which showed a progression of diabetic maculopathy, 11 eyes had developed new-onset macular edema following the cataract surgery, 11 eyes had progression of preexisting edema, and 4 of them had to undergo intravitreal anti-vascular endothelial growth factor injections as the treatment. CONCLUSION The chance of progression of DR staging is low after uncomplicated phacoemulsification, on a short term. However, the chances of worsening of macular edema as well as worsening of proliferative stages should be kept in mind while advising a patient for cataract surgery.

Abstract
Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion usually involving the head-and-neck region. On histopathological examination, it consists of reactive proliferation of endothelial cells with papillary formations which is the key to diagnosis. This rare entity was first described in 1923 by Pierre Masson. Lesions involving orbit and eyelids have been reported before. Here, we report a case of Masson's tumor which occurred in the lid margin and later in the conjunctiva which regressed completely after excision.

Abstract
Graphene has excellent unique thermal, chemical, optical, and mechanical properties such as high thermal conductivity, high chemical stability, optical transmittance, high current density, higher surface area, etc. Due to their outstanding properties, the attention towards graphene-based materials and their derivatives in wastewater treatment has been increased in recent times. Different graphene-based materials such as graphene oxides, graphene quantum dots, graphene nanoplatelets, graphene nanoribbons and other graphene-based nanocomposites are synthesized through chemical vapor deposition, mechanical and electrochemical exfoliation of graphite. In this review, the specifics about the graphenes and their derivatives, the synthesis strategy of graphene-based materials are described. This review critically explained the applications of graphene-based materials in wastewater treatment. Graphene-based materials were utilized as adsorbents, electrodes, and photocatalysts for the efficient removal of toxic pollutants such as heavy metals, dyes, pharmaceutics, antibiotics, phenols, polycyclic aromatic hydrocarbons have been highlighted and discussed. Herein, the potential scope of graphene-based material in the field of wastewater treatment is critically reviewed. In addition, a brief perspective on future research directions and difficulties in the synthesis of graphene-based material are summarized.

Abstract
Veratric acid (3,4-dimethoxy benzoic acid) (VA) is a hydrophobic phenolic phytocompound possessing therapeutic potential, but it has not been reported as actuating bone regeneration to date. Furthermore, delivery of hydrophobic compounds is often impeded in the body, thus depreciating their bioavailability. In this study, VA was found to have osteogenic potential and its sustained delivery was facilitated through a nanoparticle-embedded coaxial electrospinning technique. Polycaprolactone/polyvinylpyrrolidone (PCL/PVP) coaxial fibers were electrospun, encasing VA-loaded chitosan nanoparticles (CHS-NP). The fibers showed commendable physiochemical and material properties and were biocompatible with mouse mesenchymal stem cells (mMSCs). When mMSCs were grown on coaxial fibers, VA promoted these cells towards osteoblast differentiation as was reflected by calcium deposits. The mRNA expression of Runx2, an important bone transcriptional regulator, and other differentiation markers such as alkaline phosphatase, collagen type I, and osteocalcin were found to be upregulated in mMSCs grown on the PCL/PVP/CHS-NP-VA fibers. Overall, the study portrays the delivery of the phytocompound, VA, in a sustained manner to promote bone regeneration.

Abstract
Frenal attachments are thin folds of mucous membrane with enclosed muscle fibers that attach the lips to the alveolar mucosa and underlying periosteum. Most often, during the oral examination of the patient the dentist gives very little importance to the frenum, for assessing its morpholology and attachment. However, it has been seen that an abnormal frenum can be an indicator of a syndrome. This paper highlights the different frenal attachments seen in association with various syndromic as well as non-syndromic conditions.
