AIM To compare short-term results between laparoscopic hepatectomy and open hepatectomy using a propensity score matching. METHODS A patient in the laparoscopic liver resection (LLR) group was randomly matched with another patient in the open liver resection (OLR) group using a 1:1 allocated ratio with the nearest estimated propensity score. Patients of the LLR group without matches were excl...

LLR measures the distance between observatories on Earth and retro-reflectors Moon since 1969. In this paper, we estimate Rotation Parameters (ERP; terrestrial pole offsets, $x_p$ $y_p$, rotation phase, $\Delta$UT) using data. We values of $\Delta$UT, offsets separately. For $y_p$ together Overall, uncertainties ERP from new data (after 2000.0) have significantly improved, staying less than 20 ...

OBJECTIVES This study examined the homeostatic parameters possibly related to HIV-infected patients who, despite being under suppressive highly active antiretroviral therapy (HAART), show low-level CD4 T cell repopulation (LLR). METHODS Twenty-one LLR individuals, 20 HIV-infected controls with satisfactory CD4 T cell repopulation (R) and 14 healthy subjects were studied. Markers related to ac...

BACKGROUND Laparoscopic liver resection (LLR) is becoming an accepted treatment option for resecting both benign and malignant tumours. However, it is critical that the laparoscopic approach does not compromise the technical quality of the liver resection. The aim of this paper was to review the learning curve of LLR in a specialist HPB unit. METHODS A prospective database was searched to ide...

BACKGROUND The safety and efficacy of laparoscopic liver resection (LLR) for colorectal liver metastasis (CLM) remain to be established. A meta-analysis was undertaken to compare LLR and open liver resection (OLR) for CLM with respect to surgical and oncologic outcomes. METHODS An electronic search was performed to retrieve all relevant articles published in the English language by the end of...

The development of laparoscopic liver resection (LLR) has been slow due to technical difficulties. Therefore, LLR has been limited to easily accessible lesions. Recently, this procedure has been well applied to hepatocellular carcinoma. However, until now, the indications for LLR have been tumors in the peripheral portion of the anterolateral segments of the liver (segments II, III, V and VI an...

Selective activation of the 5-HT1A receptor induces lower lip retraction (LLR) in rats. 8-Hydroxy-dipropylamino tetralin (8-OH-DPAT)-induced LLR could not be antagonised by the 5-HT antagonists methysergide, metergoline or mesulergine. In fact, some 5-HT antagonists induced LLR. However, 8-OH-DPAT-induced LLR could be antagonised by pindolol, spiperone, spiroxatrine and NAN-190, but not by the ...

Context. The lag-luminosity relation (LLR) provides a way of estimating GRB luminosity by measuring the spectral lags between different energy bands. Aims. We want to understand the origin of the LLR and test its validity. This appears especially important if the LLR is to be used as a distance indicator. Methods. We perform a linear analysis of the lag between two spectral bands. The lag is ob...

Evoked potentials recorded from the somatosensory cortex have been shown to be an electrophysiological marker of brain injury in global hypoxic ischemia (HI). The evoked responses in somatosensory neurons carry information pertaining to signal from the ascending pathway in both the subcortical and cortical areas. In this study, origins of the subcortical and cortical signals are explored by dec...
