Microscopic Techniques for Nanomaterials Characterization: A Concise Review.

Nanomaterials have been gaining interest due to their remarkable properties at the nanoscale. The surface area of particles becomes high at the nanoscale because of this virtue, they have been used in a bundle of applications like electronics, biomedical, agriculture, wastewater treatment, semiconductor industry, cosmetics, drug delivery, paints, and so forth. The morphology (size and shape) of nanomaterials plays an important role because each application requires the appropriate morphology for better performance.

Occult Breast Cancer in High-Risk Gene-Positive Pakistani Women Undergoing Contralateral Prophylactic Mastectomy/Prophylactic Mastectomy: Implications for Sentinel Lymph Node Biopsy.

Introduction: Sentinel lymph node biopsy (SLNB) of the axilla is standard in breast cancer (BC) management; however, its role in prophylactic/contralateral prophylactic mastectomy (CPM) is still questioned. To avoid future consequences on surgical morbidity and socioeconomic aspects in low and middle-income countries (LMICs), we intend to determine the prevalence of occult breast cancer (OBC) among CPM cases.

Objective: To determine the prevalence of OBC in patients undergoing prophylactic mastectomy (PM).

Analysis of gene variants in familial and non-familial primary open angle glaucoma Pakistani patients.

Aim: To find out the association of secreted protein acidic and rich in cysteine (SPARC)-related modular calcium binding 2 () gene variants rs2255680 and rs13208776 with genotypic and phenotypic characteristics in both familial and non-familial primary open angle glaucoma (POAG) patients.

Methods: A total of 212 POAG patients, comprising 124 familial and 88 non-familial, were enrolled. For genotyping the variant rs2255680, amplification refractory mutation system (ARMS)-polymerase chain reaction (PCR) method and PCR-restriction fragment length polymorphism (PCR-RFLP) were utilized for analyzing rs13208776 variant.

Elective outpatient middle meningeal artery embolization for chronic subdural hematoma is safe.

Background: Middle meningeal artery embolization (MMAE) is a safe and effective treatment for chronic subdural hematoma (cSDH); however, the appropriate level of postoperative care is unknown.

Objective: To evaluate whether elective MMAE for cSDH could be safely performed in an outpatient setting.

Methods: This was a multicenter, retrospective study of patients with cSDH who underwent elective MMAE.
