OBJECTIVES: We aimed to assess the potential of near-infrared (NIR) imaging during minimally invasive oesophagectomy in patients with distal oesophageal cancer for detection of nodal metastases inside and outside the standard en bloc surgical field. METHODS: We enrolled 6 patients diagnosed with distal oesophageal cancer for intraoperative lymphatic mapping with NIR imaging. Indocyanine green dye was injected endoscopically in 8 corners of the primary tumour at the start of the operation...

Synchronous gynecological cancers are rarely described. Those cases account for approximately up to 6% of female genital tract malignancies. The presence of synchronous endometrial adenocarcinoma and gynecological tract neoplasia is rare - the most commonly described is synchronous adenocarcinoma and endometrial ovarian cancer (accounting for 15-20% of ovarian neoplasia and 5% of endometrial cancers). Concomitant uterine carcinosarcoma and ovarian cancer, or endometrial adenocarcinoma are extremely rare. Up till now, only 3 cases of synchronous adenocarcinoma and leiomyosarcoma were described...

BACKGROUND: Lymphatic route is one of the prominent route for improving the poor bioavailability of the drugs which undergoes extensive hepatic first pass metabolism. Nanocarriers (solid lipid nanoparticles) offers a new drug delivery system that could hold great promise for attaining the bioavailability enhancement along with controlled and site specific drug delivery. OBJECTIVE: The aim of the present research work was to prepare and optimized the Quetiapine fumarate (an antipsychotic drug) loaded solid lipid nanoparticles for lymphatic targeting through intraduodenal administration Method: Thirteen quetiapine fumarate loaded solid lipid nanoparticle formulations were developed using different lipids by Microemulsion technique and optimized by box behnken design...

Amphiphilic vaccine based on lipid-polymer conjugates is a new type of vaccine capable of self-delivering to the immune system. When injected subcutaneously, amphiphilic vaccines efficiently target antigen presenting cells in the lymph nodes (LNs) via a unique albumin-mediated transport and uptake mechanism and induce potent humoral and cellular immune responses. However, whether this new type of vaccine can be administrated via a safe, convenient microneedle-based transdermal approach remains unstudied. For such skin barrier-disruption systems, a simple application of microneedle arrays (MNs) is desired to disrupt the stratum corneum, and for rapid and pain-free self-administration of vaccines into the skin, the anatomic place permeates with an intricate mesh of lymphatic vessels draining to LNs...

We present the spontaneous pathological lesions identified as a result of necropsy or biopsy for 245 chimpanzees (Pan troglodytes) over a 35-year period. A review of the pathology database was performed for all diagnoses on chimpanzees from 1980 to 2014. All morphologic diagnoses, associated system, organ, etiology, and demographic information were reviewed and analyzed. Cardiomyopathy was the most frequent lesion observed followed by hemosiderosis, hyperplasia, nematodiasis, edema, and hemorrhage. The most frequently affected systems were the gastrointestinal, cardiovascular, urogenital, respiratory, and lymphatic/hematopoietic systems...

Huperzine A (Hup-A) is a poorly water-soluble drug with low oral bioavailability. A self-microemulsifying drug delivery system (SMEDDS) was used to enhance the oral bioavailability and lymphatic uptake and transport of Hup-A. A single-pass intestinal perfusion (SPIP) technique and a chylomicron flow-blocking approach were used to study its intestinal absorption, mesenteric lymph node distribution and intestinal lymphatic uptake. The value of the area under the plasma concentration-time curve (AUC) of Hup-A SMEDDS was significantly higher than that of a Hup-A suspension (P<0...

The long non-coding RNA (lncRNA) XLOC_006390 is increased in various human cancer tissues and it plays important roles in cell growth and migration. However, the role of lncRNA XLOC_006390 in the progression and metastasis of cervical cancer has not been evaluated and remains unclear. In the present study, we hypothesized that lncRNA XLOC_006390 is also increased in cervical cancer, and upregulation of lncRNA XLOC_006390 contributes to cervical cancer metastasis. The expression of lncRNA XLOC_006390 in cervical cancer tissues and cell lines was analyzed using quantitative reverse-transcription-polymerase chain reaction (qRT-PCR)...

The lymphatic system is an extensive vascular network that serves as the primary route for the metastatic spread of breast cancer cells (BCCs). The dynamics by which BCCs travel in the lymphatics to distant sites, and eventually establish metastatic tumors, remain poorly understood. Particle tracking techniques were employed to analyze the behavior of MCF-7 and MDA-MB-231 BCCs which were exposed to lymphatic flow conditions in a 100 μm square microchannel. The behavior of the BCCs was compared to rigid particles of various diameters (η = dp/H= 0...

We present a three-dimensional nonlinear tumor growth model composed of heterogeneous cell types in a multicomponent-multispecies system, including viable, dead, healthy host, and extra-cellular matrix (ECM) tissue species. The model includes the capability for abnormal ECM dynamics noted in tumor development, as exemplified by pancreatic ductal adenocarcinoma, including dense desmoplasia typically characterized by a significant increase of interstitial connective tissue. An elastic energy is implemented to provide elasticity to the connective tissue...

Secondary lymphedema is a common post-cancer treatment complication but the pathomechanisms underlying the disease remain unclear. Using a mouse-tail lymphedema model, we found an increase in local and systemic levels of the lymphangiogenic factor VEGF-C, and identified CD68+ macrophages as a cellular source. Surprisingly, overexpression of VEGF-C in a transgenic mouse model led to aggravation of lymphedema with increased immune cell infiltration and vascular leakage in comparison to wild-type littermates. Conversely, blockage of VEGF-C by overexpression of soluble VEGFR3 reduced edema development, diminishing inflammation and blood vascular leakage...

BACKGROUND: The southern house mosquito, Culex quinquefasciatus, is one of the most prevalent vectors of lymphatic filariasis and flavivirus-induced encephalitis. Its vectorial capacity is directly affected by its reproductive feeding behaviors, such as host seeking, blood feeding, resting, and egg laying. In mosquitoes, these gonotrophic behaviors are odor-mediated and regulated following blood feeding. Immediately after a blood meal, female mosquitoes show reduced olfactory responsiveness and flight activity, as they enter a resting state...

A controversy over the transport of chyle and lymph started a few weeks after the publication of Pecquet's Experimenta Nova Anatomica. There are records of nearly seventy people who had an active interest in this matter. Three issues were discussed: the purpose of the liver and especially its haematopoietic function, the capacity of the thoracic duct to transport all chyle, and the purpose of the lymph vessels. The controversy over the use of the lacteals and the lymph vessels subsided about 20 years after the first publication of the new theories...

Osteosarcoma is the commonest primary malignant bone tumor. Since bones lack a lymphatic system, metastatic spread in these tumors is exclusively hematogenous, the commonest sites being lungs and bone. We report a case of osteosarcoma humerus which recurred locally after primary therapy consisting of neoadjuvant chemotherapy and limb salvage surgery, who developed calcified liver metastases in addition to local and pulmonary relapse. Liver, though a common site of hematogenous spread in most solid tumors, has rarely been reported to be involved in metastatic osteosarcomas...

Immune therapy is rapidly gaining prominence in the clinic as a major weapon against cancer. Whereas much attention has been focused on the infiltration of tumors by immune cells, the subsequent fate of these infiltrates remains largely unexplored. We therefore established a photoconversion-based model that allowed us to label tumor-infiltrating immune cells and follow their migration. Using this system, we identified a population of tumor-experienced cells that emigrate from primary tumors to draining lymph nodes via afferent lymphatic vessels...

The lymphatic vascular system is a hierarchically organized complex network essential for tissue fluid homeostasis, immune trafficking, and absorption of dietary fats in the human body. Despite its importance, the assembly of the lymphatic network is still not fully understood. The zebrafish is a powerful model organism that enables study of lymphatic vessel development using high-resolution imaging and sophisticated genetic and experimental manipulation. Although several studies have described early lymphatic development in the fish, lymphatic development at later stages has not been completely elucidated...

The lymphatic system controls fluid homeostasis and the clearance of macromolecules from interstitial compartments. In mammals brain lymphatics were only recently discovered, with significant implications for physiology and disease. We examined zebrafish for the presence of brain lymphatics and found loosely connected endothelial cells with lymphatic molecular signature covering parts of the brain without forming endothelial tubular structures. These brain lymphatic endothelial cells (BLECs) derive from venous endothelium, are distinct from macrophages, and are sensitive to loss of Vegfc...

BACKGROUND: Podoconiosis, non-filarial elephantiasis, is a non-infectious disease found in tropical regions such as Ethiopia, localized in highland areas with volcanic soils cultivated by barefoot subsistence farmers. It is thought that soil particles can pass through the soles of the feet and taken up by the lymphatic system, leading to the characteristic chronic oedema of the lower legs that becomes disfiguring and disabling over time. METHODS: The close association of the disease with volcanic soils led us to investigate the characteristics of soil samples in an endemic area in Ethiopia to identify the potential causal constituents...

Long gone is the time when tumors were thought to be insular masses of cells, residing independently at specific sites in an organ. Now, researchers gradually realize that tumors interact with the extracellular matrix (ECM), blood vessels, connective tissues, and immune cells in their environment, which is now known as the tumor microenvironment (TME). It has been found that the interactions between tumors and their surrounds promote tumor growth, invasion, and metastasis. The dynamics and diversity of TME cause the tumors to be heterogeneous and thus pose a challenge for cancer diagnosis, drug design, and therapy...

Melanoma of the urogenital tract is extremely rare, accounting for less than 0.1% of melanoma cases. The global literature currently describes only 220 cases of penile melanoma, most commonly located on the glans penis. RESULTS: Penile melanoma accounts for 0.7% of penile cancers and 0.18% of melanoma cases. The average patient age for the six cases we reviewed was 44.5 years. Three of these cases (50%) involved ulceration, one case (16.7%) involved lymphovascular invasion, and three cases (50%) involved mitosis ≥ 1 mm(2) (0...
