REVIEW
Koichiro Matsuno
A reaction cycle in general or a metabolic cycle in particular owes its evolutionary emergence to the covering reaction environment acting as a measurement apparatus of a natural origin. The quantum measurement of the environmental origin underlying the molecular processes observed in the biological realm is operative cohesively between the measuring and the measured. The measuring part comes to pull in a quantum as an indivisible lump available from an arbitrary material body to be measured. The inevitable difference between the impinging quantum upon the receiving end on the part of the environment and the actual quantum pulled into the receiving end comes to effectively be nullified through the retrocausative propagation of the corresponding wave function proceeding backwards in time...

One may measure the kinetic rate constants associated with biochemical reactions using an optical biosensor: an instrument in which ligand molecules are convected through a flow cell over a surface to which receptors are immobilized. If there are multiple reactants, one is faced with the problem of fitting multiple kinetic rate constants to one signal, since data from all of the reacting species is lumped together. Even in the presence of ambiguous data, one may use a series of experiments to accurately determine the rate constants...

Extraskeletal osteosarcomas (OSs) are highly malignant soft tissue tumours associated with a poor prognosis. Only a few records of these rare aggressive neoplasms have been reported in the literature.We describe the case of a 49-year-old man, who presented to our tertiary care centre with a painful isolated lump around the umbilicus. After surgical biopsy, imaging and subsequent pathological analysis, the swelling was diagnosed to be a localised extraskeletal OS. He received previous radiation as treatment for testicular seminoma 40 years ago, which has been in remission ever since...

Proctophyllodid feather mites (400+ species) are permanent (full-time) symbionts commonly occurring on passerine birds. Phenotypic evolution of these mites appears to be greatly influenced by characters related to reproduction (>87.5% of a total of 32 taxonomically important discrete characters) and male genitalic characters (21.9%). Because sexual selection could the major evolutionary driver in this system, we test the theoretical expectation that genitalic or sexually dimorphic characters should evolve more rapidly and divergently then other characters...

Lumping kinetics models were built for the biological treatment of ABE (acetone-butanol-ethanol) fermentation wastewater by oleaginous yeast Trichosporon cutaneum with different fermentation temperatures. Compared with high temperature (33°C, 306 K) and low temperature (23°C, 296 K), medium temperature (28°C, 301 K) was beneficial for the cell growth and COD degradation during the early stage of fermentation but the final yeast biomass and COD removal were influenced little. By lumping method, the materials in the bioconversion network were divided into five lumps (COD, lipid, polysaccharide, other intracellular products, other extracellular products), and the nine rate constants (k1-k9) for the models can well explain the bioconversion laws...

Phaeohyphomycosis is an unusual granulomatous fungal infection, observed in immunocompromised or diabetic patients; however, it is even rarer in immunocompetent patients. Cytological findings of the same have been infrequently reported. The histopathological diagnosis or fungal culture helps in definitive diagnosis to identify the exact fungal species. Hereby, we report a rare case of invasive fungal infection in a breast lump in a young female, presenting as fibroadenoma breast. Fine needle aspiration cytology from the breast lesion showed the presence of septate acute-angled branching fungal hyphae with focal pigmentation, morphologically suggestive of phaeohyphomycosis which was positive with fungal stains...

Most of tumours of the foot are tumour-like (synovial cyst, foreign body reactions and epidermal inclusion cyst) or benign conditions (tenosynovial giant cells tumours, planta fibromatosis). Malignant tumours of the soft-tissue and skeleton are very rare in the foot and their diagnosis is often delayed with referral to specialised teams after initial inappropriate procedures or unplanned excisions. The adverse effect of these misdiagnosed tumours is the increasing rate of amputation or local recurrences in the involved patients...

BACKGROUND Kasabach-Merritt syndrome is a potentially fatal disease that consists of hemangioma(s) with thrombocytopenia, microangiopathic hemolytic anemia, and coagulopathy. Extensive hemangiomatosis is rare. We present the radiological features and treatment strategy of a young adult suffering from Kasabach-Merritt syndrome with widespread hemangiomas and an infected huge hematoma in the right thigh. CASE REPORT A 33-year-old Taiwanese male presented with a painful 20-cm mass over his right thigh and gross hematuria for 2 days...

Ossifying subperiosteal haematoma is an exceedingly rare manifestation of Neurofibromatosis type 1 (NF-1). We report an interesting case of plexiform neurofibroma causing a rapidly growing tibial mass as a result of subperiosteal haemorrhage, in an 11-year-old girl with previously undiagnosed NF-1. This reflects a precursor of the more mature periosteal ossification seen in cases traditionally termed "subperiosteal cysts". A previously well young girl was referred by her general practitioner with an increasingly large, mildly tender, soft lump on the anterior aspect of her right tibia...

Metaplastic breast carcinoma (MBC) is a rare type of invasive breast carcinoma, and chondroid differentiation is even rarer. Here we report a case of MBC with extensive chondroid differentiation in a 38-year-old woman who presented with a lump in her left breast. Ultrasound findings were most compatible with those of giant fibroadenoma. A histopathological examination revealed a malignant lesion comprising neoplastic epithelial cells arranged in solid nests, with large areas of chondroid differentiation. Neoplastic chondroid cells exhibited a positive reaction for S-100, patchy positive reaction for pan-cytokeratin (AE1/AE3) and negative reaction for epithelial membrane antigen...

BACKGROUND: Sarcomas are a rare type of breast malignancies and malignant peripheral nerve sheath tumors of the breast are even rarer. There are no specific clinical and radiological features for the diagnosis of this tumor and histological features are also reported to be nonspecific. Therefore, immunohistochemistry is required for its diagnosis. A definitive treatment protocol is unavailable because of its rarity. CASE PRESENTATION: We report a case of a sporadic form of breast malignant peripheral nerve sheath tumor found in a 16-year-old Asian Bangladeshi girl...

The mechanical imaging of lumps in tissues via surface measurements can permit the noninvasive detection of disease-related differences in body tissues. In routine clinical palpation, physicians frequently make decisions based on mechanical properties that they infer from tactile information felt via touch, but these examinations currently yield little quantitative information. This has motivated the development of electronic methods for mechanical imaging. However, conventional tactile sensors are rigid, unable to conform to curved geometries, and are not adaptable to the shape of all body parts, limiting their applicability in biomedical sensing applications...

The aim of this work is to study pediatric pneumatic ventricle (PVAD) performance, versus VAD rate (VADR) and native heart rate (HR) ratio Rr (VADR/HR). The study uses a hybrid model of the cardiovascular system (HCS). HCS consists of a computational part (a lumped parameter model including left and right ventricles, systemic and pulmonary arterial and venous circulation) interfaced to a physical part. This permits the connection of a VAD (15 mL PVAD). Echocardiographic and hemodynamic data of a pediatric patient (average weight 14...

The term meningocele manqué (MM) was coined in 1972 to describe a broad range of surgical findings characterized by intradural bands tethering neural structures to the dorsal dura. Over the following decades, reports continued to lump intradural tethering bands associated with a variety of comorbidities under the umbrella term MM. In more recent years, disorders previously called MM have been identified as embryologically distinct and were reclassified. While this sectioning continues, there remains a set of intradural tethering disorders for which no better term than MM exists...

This study develops an approach based on hierarchical cluster analysis for investigating the spatial and temporal variation of water quality governing processes. The water quality data used in this study were collected in the karst aquifer of Yucatan, Mexico, the only source of drinking water for a population of nearly two million people. Hierarchical cluster analysis was applied to the quality data of all the sampling periods lumped together. This was motivated by the observation that, if water quality does not vary significantly in time, two samples from the same sampling site will belong to the same cluster...

Quarter vehicle model is the simplest representation of a vehicle that belongs to lumped-mass vehicle models. It is widely used in vehicle and suspension analyses, particularly those related to ride dynamics. However, as much as its common adoption, it is also commonly accepted without quantification that this model is not as accurate as many higher-degree-of-freedom models due to its simplicity and limited degrees of freedom. This study investigates the trade-off between simplicity and accuracy within the context of quarter vehicle model by determining the effect of adding various modeling details on model accuracy...

Abdominal wall tumors are sometimes diagnosed as metastases of ovarian cancer, however, primary peritoneal tumors should be taken into consideration in the final diagnosis. A 49-year-old female patient was admitted in our Department for the excision of a pulpable abdominal wall lump, with no other abnormalities shown on imaging investigation. On histology examination, the excised specimen revealed characteristics of metastatic high-grade serous ovarian carcinoma. Total hysterectomy, bilateral oophorectomy, omentectomy and appendectomy were performed...
