The rapid growth of therapeutic monoclonal antibodies demands greater accessibility to scalable methods of evaluating antigen binding. Homogenous TR-FRET is ideal for preliminary screening but has not been reported to assay these interactions due to their high-affinity and complex solution-phase kinetics. Here we report the development of a competition assay to rank-order the relative affinities of these drugs for a common antigen.

Basal cell carcinoma (BCC) of the ear may have aggressive histologic subtypes and a greater propensity for subclinical spread than BCC in other anatomic locations. In this retrospective analysis, we evaluated recurrence rates of BCC of the ear in 102 patients who underwent treatment with Mohs micrographic surgery (MMS) or radiation therapy (RT) at a single institution between January 2017 and December 2019. Data on patient demographics, tumor characteristics, treatment modality, and recurrence rates were collected from medical records.

Background: While there is a higher risk of surgical site infection (SSI) on the lower extremities following Mohs micrographic surgery (MMS), antibiotic prophylaxis (AP) is debated.

Objective: To determine the role of shared decision making (SDM) in guiding AP usage during MMS on the lower extremities.

Materials And Methods: A prospective observational study was conducted whereby patients received a standardized SDM discussion or routine counseling.

Article Synopsis
  • Pinch grafting has gained renewed interest due to its simplicity and safety, primarily used for chronic nonhealing wounds and post-surgical applications, especially in the lower limbs.
  • A systematic review analyzed studies from 2000 onwards, identifying 10 articles involving 335 patients treated with pinch grafts, showcasing its effectiveness in healing skin ulcers and as an alternative to primary closure after cancer removal.
  • Results indicated that pinch grafting is a safe and effective method, but further research is needed as only 10% of cases explored its use in dermatologic surgery.

Article Synopsis
  • Hidradenocarcinoma (HAC) is a rare type of skin cancer, and this study aims to provide the first systematic review and update on its diagnosis and management based on existing data and a case series from the authors' institution.* -
  • The research analyzed 225 studies with 165 HAC cases, revealing that HAC typically presents in 60-year-old patients, predominantly affecting the head and neck region, with over a third of cases presenting or progressing to metastatic disease.* -
  • Early detection and correct histological evaluation are essential for HAC, with wide local excision being the main treatment option; however, Mohs micrographic surgery may offer better outcomes and lower metastasis risk.*

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) and primary cutaneous mucinous carcinoma (PCMC) are rare low-grade neoplasms thought to arise from apocrine glands that share many histological features and are proposed to be on a single histopathologic continuum, with EMPSGC as the in situ form that may progress to the invasive PCMC. Management involves a metastatic workup and either wide local excision (WLE) with greater than 5 mm margins or Mohs micrographic surgery (MMS) in anatomically sensitive areas. We present 2 cases of EMPSGC and 3 cases of PCMC and review their clinical and histopathologic features, differential diagnoses, and treatment.

Background: Lidocaine is the most commonly used local anesthetic for Mohs micrographic surgery (MMS), but given its limited half-life, postoperative pain remains a significant concern for patients. Bupivacaine is used in various surgical subspecialty procedures and has demonstrated improved pain control compared with lidocaine. However, its role in MMS is insufficiently explored.

Neurotropic melanoma is a rare type of malignant melanoma with nerve invasion or neural differentiation. Neurocristic cutaneous hamartoma is a rare, benign tumor of the skin and superficial soft tissue that arises from aberrant migration of neural crest cells. We report a rare case of a 74-year-old man with a clinically diagnosed giant congenital nevus of the right mid-back, histopathologically confirmed to be a neurocristic cutaneous hamartoma, who developed neurotropic spindle cell melanoma within the lesion.

Background: Extraocular sebaceous carcinoma (SC) is rare, with distinct features from its ocular counterpart. These neoplasms have been associated with Muir-Torre syndrome (MTS). Associated internal malignancies include gastrointestinal and genitourinary.

Absolute glycoproteomics quantification has drawn tremendous attention owing to its prospects in biomarker discovery and clinical implementation but is impeded by a general lack of suitable heavy isotope-labeled glycopeptide standards. In this study, we devised a facile chemoenzymatic strategy to synthesize a total of 36 human IgG glycopeptides attached with well-defined glycoforms, including 15 isotope-labeled ones with a mass increment of 6 Da to their native counterparts. Spiking of these standards into human sera enabled simplified, robust, and precise absolute quantification of IgG glycopeptides in a subclass-specific fashion.

Acclimation by plants to hypoxia and anoxia is of importance in various ecological systems, and especially for roots in waterlogged soil. We present evidence for acclimation by roots via 'anoxic' cores rather than being triggered by O sensors. The evidence for 'anoxic' cores comes from radial O profiles across maize roots and associated metabolic changes such as increases in the 'anaerobic enzymes' ADH and PDC in the 'anoxic' core, and inhibition of Cl transport to the xylem.

Background: Basal cell carcinoma (BCC) is a common tumor but rarely presents on nonexposed skin. We sought to identify and characterize the traits of the malignancy over a 10-year period.

Methods: A retrospective chart review of all BCCs between 2007 and 2017 was performed.

Many of the profound changes in metabolism that are caused by O2 deficiency also occur in well-aerated tissues when oxidative phosphorylation is partially or wholly inhibited. For these well-aerated tissues, reduction in energy formation occurs during exposure to inhibitors of oxidative phosphorylation, cold/chilling and wounding, so we prefer the term 'energy crisis' metabolism over 'anaerobic' metabolism. In this review, we note that the overwhelming body of data on energy crises has been obtained by exposure to hypoxia-anoxia, which we will indicate when discussing the particular experiments.

A novel synthesis of nucleotide sugars was conducted to prepare UDP-α-D-xylose and UDP-β-L-arabinose without utilizing protection strategies or advanced purification techniques. Sugar-1-phosphates of D-xylose and L-arabinose were synthesized from their β-glycosylsulfonylhydrazides and evaluated as substrates for recombinant UDP-sugar pyrophosphorylases from or to furnish the biologically active nucleotide. The facile, three-step procedure takes advantage of substrate diversity available through chemical synthesis followed by the selectivity of enzyme catalysis.

Background And Aims: Our aim was to elucidate how plant tissues under a severe energy crisis cope with imposition of high NaCl, which greatly increases ion fluxes and hence energy demands. The energy requirements for ion regulation during combined salinity and anoxia were assessed to gain insights into ion transport processes in the anoxia-tolerant coleoptile of rice.

Methods: We studied the combined effects of anoxia plus 50 or 100 mm NaCl on tissue ions and growth of submerged rice (Oryza sativa) seedlings.

Background: Venous ulcers are very common with few curative treatment options.

Objective: To report the closure rate and clinical characteristics of active venous ulcers in a vein clinic using endovenous laser ablation (EVLA) with a 1,320-nm laser.

Methods And Materials: A prospective database was kept consisting of patients with an active venous ulcer at the time of consultation in a single-practitioner academic vein clinic from March 2007 to May 2014.

Acral calcified angioleiomyoma is an uncommon tumor that presents as a non-descript papule or subcutaneous nodule, classically on the foot. Biopsy or excision is typically the diagnostic method of choice as well as the treatment for these sometimes painful tumors. We report an uncommon clinical presentation of acral calcified angioleiomyoma with considerable extrusion of calcium perforating through the skin.
