Metacercariae in fishes of Sun Moon lake which is an endemic area for Clonorchis sinensis in Taiwan.

The Sun Moon lake in Central Taiwan is a known endemic area for clonorchiasis. Of the 45 fresh water fish, Hemiculter leucisculus, from the lake that were examined by artificial gastric juice digestion in October 1995, all were found to harbor metacercariae in their muscle. The number of metacercariae isolated from each fish ranged from 2 to 2,185, with an average of 254. A total of 11,443 metacercariae was collected from the 45 fish. Of the 4,223 metacercaria that were examined under light microscope, 4,064 (96.23%) were found to belong to Haplorchis taichui, 90(2.13%) to H. pumilio, 2(0.05%) to C. sinensis and 67 (1.59%) to unknown species due to the metacercariae being not yet developed or immature. The 2 C. sinensis metacercariae were obtained from 2 out of 45 fish examined. Our results contrast with reports of a decade ago which stated that all the fish of the Sun Moon lake examined were positive for C. sinensis. Possible reasons for the decrease of C. sinensis metacercariae are the disappearance of pig farms around the lake, increased awareness of the trematode by the lakeside inhabitants and probably the exclusive use of mammals as its definitive host by C. sinensis. In contrast, besides mammals, Haplorchis spp also use birds as their definitive hosts.

Laurence-Moon-Biedl syndrome (?) and Prader-Willi syndrome (?) in a single family.

Mental retardation, hypogonadism, obesity, and abnormal blood sugar regulation were common findings in two siblings. In addition, the 17-year-old female patient showed short stature, muscular hypotonia in infancy, and small hands with tapering fingers suggesting Prader-Willi syndrome, and the 12-year-old male patient showed retinitis pigmentosa, normal height, and normal muscular tonicity suggesting Laurence-Moon-Biedl syndrome, though polydactyly was absent. Possible consideration was discussed.

Does the moon influence the predatory activity of mites?

Periodicity in predatory activity was observed in overwintered females of Typhlodromus pyri Scheuten (Acari: Phytoseiidae). Chronobiometrical analysis revealed that an approximately circabiseptan (about-14-day) rhythm is statistically significant, with a striking depression around the full moon.

Laurence-Moon-Biedl syndrome: scintigraphic appearance of kidneys.

We report a 7-year-old child with Laurence-Moon-Biedl syndrome, an autosomal recessive syndrome, with impaired renal function detected by means of technetium-99m diethylenetriamine-pentaacetic acid (Tc-99m DTPA), technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) scintigraphy, and ultrasonography. The altered renal morphology and decreased renal functions are documented.

Skeletal abnormalities of hands and feet in Laurence-Moon-Bardet-Biedl (LMBB) syndrome: a radiographic study.

OBJECTIVE: To identify radiological changes of the hands and feet in a large group of patients with Laurence-Moon-Bardet-Biedl syndrome. DESIGN: Postero-anterior views of hands and feet were obtained and analysed. PATIENTS: The material consists of 43 Scandinavian patients with the syndrome (24 males and 19 females; age 3 weeks to 57 years, median 23 years at the time of radiological examination). RESULTS AND CONCLUSIONS: Polydactyly of the hands and feet is one of the main criteria. This was noted clinically in 33 of 43 patients, but all but 3 had been operated on before this radiological study. Remnants of the extirpated finger or toe noted as exostoses, additional joint surfaces of duplication were found in half the hands and feet, while the remainder showed no radiological changes. Other features found were short, broad bones and flat joint surfaces of the metacarpophalangeal or metatarsophalangeal joints. We also found a high frequency of short or long ulna in relation to the radius and Madelung deformity of the wrist in several patients. Thus, the radiographs showed several non-specific normal variations besides remnants or postoperative changes after polydactyly.

Simulation of gait and gait initiation associated with body oscillating behavior in the gravity environment on the moon, mars and Phobos.

A double-inverted pendulum model of body oscillations in the frontal plane during stepping [Brenière and Ribreau (1998) Biol Cybern 79: 337-345] proposed an equivalent model for studying the body oscillating behavior induced by step frequency in the form of: (1) a kinetic body parameter, the natural body frequency (NBF), which contains gravity and which is invariable for humans, (2) a parametric function of frequency, whose parameter is the NBF, which explicates the amplitude ratio of center of mass to center of foot pressure oscillation, and (3) a function of frequency which simulates the equivalent torque necessary for the control of the head-arms-trunk segment oscillations. Here, this equivalent model is used to simulate the duration of gait initiation, i.e., the duration necessary to initiate and execute the first step of gait in subgravity, as well as to calculate the step frequencies that would impose the same minimum and maximum amplitudes of the oscillating responses of the body center of mass, whatever the gravity value. In particular, this simulation is tested under the subgravity conditions of the Moon, Mars, and Phobos, where gravity is 1/6, 3/8, and 1/1600 times that on the Earth, respectively. More generally, the simulation allows us to establish and discuss the conditions for gait adaptability that result from the biomechanical constraints particular to each gravity system.

Renal involvement in the Laurence-Moon-Bardet-Biedl syndrome: report of five cases.

We report five patients with Laurence-Moon-Bardet-Biedl syndrome (LMBBS) who had renal involvement. Intravenous pyelography showed bilateral or unilateral calyceal clubbing and blunting in all patients. In addition, one patient had a parapelvic cyst in the left kidney and another had bilateral lobulated renal outlines of the fetal type. One patient had a urinary concentrating defect and two patients showed increased fractional sodium excretion. Estimated tubular phosphate reabsorption values were in normal limits in all of five patients. No patient had a urine acidification defect, proteinuria, glycosuria, or hyperaminoaciduria. One patient died from end-stage renal failure. The remaining four patients had normal serum creatinine values and estimated creatinine clearances. 99mTechnetium-diethylenetriamine pentaacetate renal scanning showed prolonged and delayed concentration and delayed excretion in three of the four patients who survived. A focal scar was determined on the left kidney of one of four patients by 99mtechnetium-dimercaptosuccinic acid renal scanning. All LMBBS cases with or without renal symptoms should be routinely evaluated for renal abnormalities. Renal scanning is a valuable method, especially for determining the renal involvement in the early stage of disease.

Biogenerative life-support system: farming on the moon.

Plants can be used to recycle food, oxygen, and water in a closed habitat (e.g., on the moon, Mars, or in a space craft. A variety of crops might be grown, probably in underground growth units to avoid harmful radiation and micrometeorites. Artificial light will be necessary although some sunlight might be brought in via fiber optics. Transpired water will be condensed in coils exposed to space and shaded from sunlight. Oxygen and CO2 levels will be maintained by controlling photosynthesis and waste oxidation. Plants will be grown hydroponically. Wheat has been produced at the rate of 60 g m-2 d-1, which could feed a human continuously from a farm only 13 m2, but nearly continuous light equivalent to sunlight is required along with ideal temperatures, enriched CO2, suitable cultivars, etc. Lower light results in more efficient photosynthesis but requires a larger farm, as do safety considerations and many crops.

The Laurence-Moon-Bardet-Biedl syndrome: unresponsiveness to the action of testosterone, a possible mechanism.

The pathogenesis of hypogonadism and hypogenitalism was investigated in a male patient with the complete form of the Laurence-Moon-Bardet-Biedl syndrome. Synthetic gonadotropin-releasing hormone induced an increase in serum luteinizing hormone levels from 16.5 mIU/ml to 19.3 mIU/ml and in follicle-stimulating hormone levels from 18.5 mIU/ml to 25.9 mIU/ml. Serum testosterone levels were normal and did not rise after stimulation with human chorionic gonadotropin. The administration of thyrotropin-releasing hormone resulted in an increase in serum thyrotropin levels from 9.0 microU/ml to 12.0 microU/ml. Serum testoterone/estradiol-binding globulin, adrenocorticotropic hormone, and T3 resin uptake were normal. Serum cortisol showed a normal diurnal variation. The sex chromatin test was negative and the karyotupe revealed a 46,XY chromosome pattern. On biopsy, the left testis lacked germinal cells and the right testis showed spermatogenic arrest. Signs of hypogonadism and hypogenitalism persisted after 11 months of testosterone treatment. In this patient the target-organ unresponsiveness resulted in hypogenitalism and hypogonadism.

The renal lesion of the Laurence-Moon-Biedl syndrome.

In nine children with the Laurence-Moon-Biedl syndrome a high incidence of nephropathy was documented. Renal involvement was noted in seven patients before or simultaneously with the diagnosis of LMBS. Five have uremia and two have died. All patients had an abnormal urogrum. The spectrum of renal lesions ranged from mesangial tissue proliferation to glomerular clerosis, interstitial scarring, and medullary and cortical cyst formation. A relationship between the lesions seen in the LMBS and those of other hereditary retinal-renal conditions is suggested.

The pituitary gland in the Laurence-Moon syndrome.

The apparent hypogonadism in patients with the Laurence-Moon syndrome has been variably attributed to unresponsiveness of target organs to gonadal hormones, primary end-organ failure, hypothalamic dysfunction, or pituitary failure. We report the first immunocytologic study of the pituitary gland in this rare disorder. No morphologic abnormalities were noted. The numbers and immunoreactivities of adenohypophyseal cell types were normal. No microscopic abnormalities were evident in the hypothalamus and target organs. The results of our study are consistent with recent biochemical data that suggest that pituitary function is normal in patients with this syndrome.

Lunar nodal tide and distance to the Moon during the Precambrian.

The pace of tidal evolution for the past approximately 450 Myr implies an Earth/Moon collision some 1,500-2,000 Myr BP, an event for which there is no corroborating evidence. Here we present the first direct determination of the lunar distance in the Precambrian. We interpret a 23.3 +/- 0.3-yr periodicity preserved in a 2,500 Myr BP Australian banded iron formation (BIF) as reflecting the climatic influence of the lunar nodal tide, which has been detected with its modern 18.6-yr periodicity in some modern climate records. The lunar distance at 2,500 Myr BP would then have been about 52 Earth radii. The implied history of Precambrian tidal friction is in accord with both the more recent palaeontological evidence and the long-term stability of the lunar orbit. The length of the Milankovitch cycles that modulate the ice ages today also evolve with the Earth-Moon system. Their detection in the Precambrian sedimentary record would then permit an independent determination of the lunar distance.

Quadriparesis in the Laurence-Moon-Biedl-Bardet syndrome: case report.

A 36 year old patient known to suffer from the Laurence-Moon-Biedl-Bardet syndrome (LMBBS) developed spastic quadriparesis. The typical features of the syndrome, presented by this patient were polydactyly, obesity, hypogonadism, retinitis pigmentosa and relative mental retardation. Severe spinal cervical and lumbar canal stenosis imaged by plain X-rays and computerised tomography was found. Magnetic resonance imaging showed significant atrophy of the spinal cord, indicating that the cause of the quadriparesis was cervical myelopathy. The patient underwent laminoplasty with some improvement.

[Dogs, man-wolves and full moon].

According to a study of the British Medical Journal in England the incidence of dog bites increases at the time of a full moon. The following article first passes the myths dealing with the werewolf. By changing from delinquent to patient during the Enlightenment the werewolf gets important to the history of medicine and psychiatry. From the anthropological point of view the so-called Lycorexia may be understood as an unconscious effort to undo evolution by transformation into beast. By the figure of the "Huckup" in recent variants concerning the werewolf subject a psychological turn of the legend is expressed.
