A rare optineurin mutation in an Indian family with coexistence of JOAG and PCG.

Purpose: This study focused on the genetic screening of Myocilin (MYOC), Cytochrome P450 family 1 subfamily B member 1 (CYP1B1), Optineurin (OPTN), and SIX homeobox 6 (SIX6) genes in a family with coexistence of primary congenital glaucoma (PCG) and juvenile open-angle glaucoma (JOAG).

Methods: Sanger sequencing was used to examine the coding region of all four genes. Six different online available algorithms were used for the pathogenicity prediction of missense variant.

Re-inventing the straight incision with a single central suture in manual small-incision cataract surgery to minimize surgically induced astigmatism.

Purpose: To calculate the surgically induced astigmatism (SIA) in MSICS through a superiorly placed straight scleral incision closed with a single, central, perpendicular 10-0 polyamide suture and to document any suture-related complaints and complications.

Methods: A retrospective, hospital-based study was carried out in 50 cases of uncomplicated senile cataract (>50 year) with nuclear sclerosis ≥ grade 4, "with the rule" astigmatism who underwent MSICS through a superior, straight incision with a single, central, perpendicular 10-0 nylon suture. Patients with "against the rule" astigmatism, keratoconus, pre-existing corneal opacity, astigmatism >2D, distorted or oblique mires, and previous ocular surgeries and unwilling to participate were excluded.

Methods: This study included a total of 1400 children aged 5-16 years in a district in North India. Visual acuity was measured using a Snellen's chart.

A study to evaluate ocular changes in patients undergoing spine surgery in the prone position.

Background And Aims: AA present prospective study was conducted to evaluate ocular changes occurring in patients undergoing spine surgery in the prone position.

Material And Methods: A total of 44 patients of either sex, belonging to American society of Anaesthesiology I and II (aged 18-60 years) scheduled for elective spine surgery in prone position were enrolled in the study. Baseline IOP and MAP measurement were taken prior to induction.

Nanosheets of Nonlayered Aluminum Metal-Organic Frameworks through a Surfactant-Assisted Method.

During the last decade, the synthesis and application of metal-organic framework (MOF) nanosheets has received growing interest, showing unique performances for different technological applications. Despite the potential of this type of nanolamellar materials, the synthetic routes developed so far are restricted to MOFs possessing layered structures, limiting further development in this field. Here, a bottom-up surfactant-assisted synthetic approach is presented for the fabrication of nanosheets of various nonlayered MOFs, broadening the scope of MOF nanosheets application.

Sensitive and Reversible Detection of Methanol and Water Vapor by In Situ Electrochemically Grown CuBTC MOFs on Interdigitated Electrodes.

The in situ electrochemical growth of Cu benzene-1,3,5-tricarboxylate (CuBTC) metal-organic frameworks, as an affinity layer, directly on custom-fabricated Cu interdigitated electrodes (IDEs) is described, acting as a transducer. Crystalline 5-7 µm thick CuBTC layers are grown on IDEs consisting of 100 electrodes with a width and a gap of both 50 µm and a height of 6-8 µm. These capacitive sensors are exposed to methanol and water vapor at 30 °C.

Cow Urine Keratopathy: A Case Report.

Injury to the ocular surface has been described to occur with a wide variety of chemicals. In most cases the cause is industrial injury with acids or alkalis. We are reporting a case of ocular surface injury due to "Cow urine" which to the best of our knowledge is been reported for the first time.

Gas Phase Sensing of Alcohols by Metal Organic Framework-Polymer Composite Materials.

Affinity layers play a crucial role in chemical sensors for the selective and sensitive detection of analytes. Here, we report the use of composite affinity layers containing Metal Organic Frameworks (MOFs) in a polymeric matrix for sensing purposes. Nanoparticles of NH-MIL-53(Al) were dispersed in a Matrimid polymer matrix with different weight ratios (0-100 wt %) and drop-casted on planar capacitive transducer devices.

Recent trends: Medical management of infectious keratitis.

This review article highlights the newer diagnostic modalities and approaches in the medical management of infectious keratitis. A Medline literature search conducted to March 2014 has been included. Recent studies or publications were selected from international indexed journals using suitable key words.

Contactless photoconductance study on undoped and doped nanocrystalline diamond films.

Hydrogen and oxygen surface-terminated nanocrystalline diamond (NCD) films are studied by the contactless time-resolved microwave conductivity (TRMC) technique and X-ray photoelectron spectroscopy (XPS). The optoelectronic properties of undoped NCD films are strongly affected by the type of surface termination. Upon changing the surface termination from oxygen to hydrogen, the TRMC signal rises dramatically.

Synthesis and biological evaluation of some novel pyrazolopyrimidines incorporating a benzothiazole ring system.

In the present study, a series of benzothiazol derivatives 3a-l containing pyrazolo[3,4-d]pyrimidine moiety at the second position were synthesized and characterized by analytical and spectral data. The compounds were tested for their in vitro antimicrobial activity. Compounds 1-(1,3-benzothiazol-2- yl)-3-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine (3a), 1- (1,3-benzothiazol-2-yl)-4-(4-chlorophenyl)-3-methyl-1H-pyrazolo[ 3,4-d]pyrimidine (3d) and 1-(1,3-benzothiazol-2-yl)- 3-methyl-4-substituted phenyl-1H-pyrazolo[3,4-d]pyrimidines (3h-j) showed significant inhibitory activity against P.

Tractor nail as impacted foreign body: rare case scenario.

A patient presented with a metallic nail impacted in the right orbital floor after being hit by a projectile. The nail was disimpacted and removed as guided by the radiograph image. Radiography proved helpful in forming a coherent scheme for case management.

Study of some common biochemical bone turnover markers in postmenopausal women.

Markers of bone formation in serum include total and bone specific alkaline phosphatase, osteocalcin and Type 1 collagen carboxy terminal extension peptide. Bone resorption can be assessed by measuring plasma tartarate resistant acid phosphtase and urinary excretion of collagen degradation products: hydroxyproline, hydroxylysine glycosides and more recently the pyridinium crosslinks and associated peptides. We compared the excretion of hydroxyproline in women of reproductive age group to those of menopausal age group and found a significant difference in the two age groups.
