Understanding intrinsic and extrinsic drivers of reproductive success is central to advancing animal ecology and characterizing critical habitat. Unfortunately, much of the work examining drivers of reproductive success is biased toward particular groups of organisms (e.g., colonial birds, large herbivores, capital breeders). Long-lived mammalian carnivores that are of conservation concern, solitary, and territorial present an excellent situation to examine intrinsic and extrinsic drivers of reproductive success, yet they have received little attention...

Endoscopic surgery is now standard of care for different Endocrine Disorders; the endoscopic thyroid surgery is becoming more popular and different approaches has been practice by many thyroid surgeon worldwide. Trans-orovestibular approach, based on the principle of natural orifice transluminal surgery is truly scar free thyroid surgery and has minimal dissection. We are presenting here three cases of benign solitary thyroid nodule operated endoscopically through trans-oro-vestibular approach in one male and two female patients...

Though the association between follicular carcinoma and bone metastasis is well established, the site-wise distribution is not known. One hundred seventy-three patients of follicular carcinoma presenting between 2003 and 2011 were selected from 1093 patients of follicular lesions presenting at a single institution. Of these, 59 (34%) with bone metastasis were included in the study. Fifty of the 59 patients (84.7%) had metastasis at presentation, while 9 developed bone metastasis during follow-up. Sixty-one percent had solitary metastasis, 15 (25...

Neurofibromas are benign peripheral nerve sheath tumours, which are usually solitary and sporadic. Solitary neurofibromas of the breast are rare. The most common location of a breast neurofibroma is the nipple-areola complex. We report a rare case of a 56-year-old woman with a solitary neurofibroma of the right breast sulcus.

We report a rare case of primary pulmonary synovial sarcoma that underwent spontaneous regression after a transbronchial biopsy. A 38-year-old woman with a well-demarcated solitary mass shadow on chest roentgenogram was referred to us. A transbronchial biopsy was performed, and immunohistochemical results as well as detection of SYT-SSX1 (SYnovial sarcoma Translocation-Synovial Sarcoma X chromosome breakpoint) transcripts resulted in a diagnosis of synovial sarcoma. A right lower lobectomy was performed during video-assisted thoracoscopic surgery...

The mechanisms of injured brain that establish poststroke seizures and epilepsy are not well understood, largely because animal modeling has had limited development. The main objective of this study was to determine whether an arterial occlusion model of cortical stroke in young adult and aged rats was capable of generating either focal or generalized epileptic seizures within 2 months of lesioning. Four- and 20-month-old male Fischer 344 (F344) sham-operated controls and those lesioned by transient (3 h) unilateral middle cerebral artery (MCA) and common carotid artery (CCA) occlusion (MCA/CCAo) were studied by video-EEG recordings up to 2 months post-procedure...

Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion...

BACKGROUND: Uncommon primary hepatic malignancies such as intrahepatic cholangiocarcinoma (ICC) and hepatocholangiocarcinoma (HCC-CC) were generally considered contraindications for liver transplantation(LT), and studies comparing the efficacy of LT and resection (LR) for ICC/HCC-CC were scarce. OBJECTIVE: To compare the survival outcomes of ICC/HCC-CC patients treated by LT and LR in a propensity score-matched population. METHOD: This is a retrospective study from 1995 to 2015...

Currently, effective phonons (renormalized or interacting phonons) rather than solitary waves (for short, solitons) are regarded as the energy carriers in nonlinear lattices. In this work, by using the approximate soliton solutions of the corresponding equations of motion and adopting the Boltzmann distribution for these solitons, the average velocities of solitons are obtained and are compared with the sound velocities of energy transfer. Excellent agreements with the numerical results and the predictions of other existing theories are shown in both the symmetric Fermi-Pasta-Ulam-β lattices and the asymmetric Fermi-Pasta-Ulam-αβ lattices...

Unlike the Hodgkin-Huxley picture in which the nerve impulse results from ion exchanges across the cell membrane through ion-gate channels, in the so-called soliton model the impulse is seen as an electromechanical process related to thermodynamical phenomena accompanying the generation of the action potential. In this work, account is taken of the effects of damping on the nerve impulse propagation, within the framework of the soliton model. Applying the reductive perturbation expansion on the resulting KdV-Burgers equation, a damped nonlinear Schrödinger equation is derived and shown to admit breathing-type solitary wave solutions...

Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis (PLCA), which presents as discrete, firm, closely-set 1-3mm, dome-shapedbrown papules commonly involving the anterior aspect of shins and extensor surfaces of forearms. We present a case of an otherwise healthy man in his 30s with solitary facial involvement of lichen amyloidosis, which is very uncommon.

Collagenoma is a type of connective tissue nevi, a rare hamartomatous malformation characterized by the predominant proliferation of normal collagen fibers and normal, decreased, or increased elastic fibers. Collagenomas present as multiple or solitary, hereditary or sporadic, asymptomatic, skin-colored papules, nodules, and plaques with variable sizes, and are usually located on the trunk, arm, and back. Here, we report on a 14-year-old boy who presented with an isolated giant collagenoma of the frontal area that dramatically responded to intralesional triamcinolone acetonide...

Microvenular hemangioma (MVH) is an acquired, benign type of hemangioma that usually manifests itself as a solitary, slowly growing, red to violaceous, asymptomatic papule, plaque or nodule. It is typically located on the trunk or extremities of young adults. It can be difficult to differentiate MVH from other types of hemangioma and Kaposi sarcoma. Herein we report a case of MVH unusual for its location, age of onset, and morphologic features. A 62-year-old man complained of an asymptomatic, bluish-red discoloration on the tip of his nose that had been present for two years...

The increasing resistance of human pathogens severely limits the efficacy of antibiotics in medicine, yet many animals, including solitary beewolf wasps, successfully engage in defensive alliances with antibiotic-producing bacteria for millions of years. Here, we report on the in situ production of 49 derivatives belonging to three antibiotic compound classes (45 piericidin derivatives, 3 streptochlorin derivatives, and nigericin) by the symbionts of 25 beewolf host species and subspecies, spanning 68 million years of evolution...

Primary cutaneous small/medium-sized pleomorphic T-cell lymphoproliferative disorder (PCSM-TCLPD) is a rare and indolent primary cutaneous T-cell lymphoma variant [1], usually presenting as a solitary nodule or plaque in the head and neck [2] or rarely as multiple lesions in anatomic areas apart from head and neck [2]. Histology reveals the presence of a dense dermal infiltrate of CD4+, CD8-, small/medium pleomorphic cells [2] intermingled with reactive cells. Surgical or radiotherapic approach are the preferred option, while oral doxycycline has been suggested in cases with multiple lesions [2-3]...

Solitary bees are important but declining wild pollinators. During daily foraging in agricultural landscapes, they encounter a mosaic of patches with nest and foraging habitat and unsuitable matrix. It is insufficiently clear how spatial allocation of nesting and foraging resources and foraging traits of bees affect their daily foraging performance. We investigated potential brood cell construction (as proxy of fitness), number of visited flowers, foraging habitat visitation and foraging distance (pollination proxies) with the model SOLBEE (simulating pollen transport by solitary bees, tested and validated in an earlier study), for landscapes varying in landscape fragmentation and spatial allocation of nesting and foraging resources...

Neurilemmoma (NL), also termed schwannoma, presents as a well-circumscribed and encapsulated mass in the human body and is almost always solitary. CT scan of a patient with NL shows a round, ovoid, or lobulated well-demarcated solid mass of soft tissue density. Primary intrathoracic neurogenic tumors location varies. However, the development of such tumors is by far more common in the costovertebral angle of the posterior mediastinum. Here, we report a rare case of a 43-year-old patient, never smoker and previously healthy, who presented with a mass adjacent to the right pulmonary hilum...
