This work illustrates a novel prototype of a transmittance hyperspectral imaging (HSI) scanner, operating in the 400-900 nm range, and designed on purpose for non-invasive analysis of photographic materials, such as negatives, films and slides. The instrument provides high-quality spectral data and high-definition spectral images on targets of small size (e.g., 35 mm film strips) and is the first example of HSI instrumentation specifically designed for applications in the photographic conservation field. The instrument was tested in laboratory and on a set of specimens selected from a damaged photographic archive. This experimentation, though preliminary, demonstrated the soundness of a technical approach based on HSI for large-scale spectroscopic characterization of photographic archival materials. The obtained results encourage the continuation of experimentation of HSI as an advanced tool for photography conservation.

The Pediatric Hip Physical Exam.

Purpose Of Review: Atraumatic hip pain in children is one of the most common orthopaedic complaints in this population. This review details the important elements of the pediatric hip physical exam and provides an overview of pertinent clinical exam findings in specific diagnoses of common pediatric hip pathology.
Recent Findings: A thorough physical exam is critical for the diagnosis of pediatric hip pathology, as many conditions have exam findings that are very commonly associated with the pathology, if not pathognomonic for the disorder.

Purpose: This study aimed to identify if a subset of men can safely avoid or delay prostate biopsy based on negative results of prostate-specific membrane antigen positron emission tomography (PSMA-PET).
Materials And Methods: Among 341 consecutive cases in a prospective biopsy cohort (NCT05073653), 111 treatment-naïve men with negative PSMA-PET (PRIMARY-score 1/2) were included. All participants underwent PSMA-PET and histopathological examinations.
Climate Change-Induced Decline in Succulent in Namibia's Arid Regions.

Department of Plant and Soil Sciences, University of Pretoria, Hatfield, Pretoria P.O. Box X20, South Africa.
The global rise in temperatures due to climate change has made it difficult even for specialised desert-adapted plant species to survive on sandy desert soils. Two of Namibia's iconic desert-adapted plant species, and the quiver tree , have recently been shown to be under threat because of climate change. In the current study, three ecologically important Namibian milk bushes were evaluated for their climate change response.

Objective: To evaluate the wound healing of recipient and donor sites following keratinized mucosa augmentation (KMA) around implants in reconstructed jaw areas and to compare these outcomes with gingival grafts in native jawbone, so as to provide clinical guidance for postoperative maintenance, and to investigate the impact of clinical experience on the evaluation of KMA postoperative healing through subgroup comparisons.
Methods: This study included patients who underwent resection of maxillofacial tumors, fibular or iliac flap reconstruction, and implant placement at Peking University Dental Hospital from October 2020 to April 2023. Three months post-implant placement, the patients were referred for KMA procedures.

Purpose: The primary objective of this study was to investigate the possible role and assess the potential relationship of speculum use during phacoemulsification surgery in the occurrence of blepharoptosis.
Methods: Our study is a prospective observational design to analyze patients who underwent phacoemulsification surgery under topical anesthesia between October 2017 and May 2018 at a tertiary eye hospital in South India. All patients had their Margin Reflex Distance 1 (MRD1), levator palpebrae superioris (LPS) function, and lid crease distance (LCD) measured before and after surgery on day one, one month, three months, and six months to evaluate the extent of ptosis at each time point that was recorded clinically and photographic documentation for accurate evaluation.
